When I introduced this dependency it looked like a good idea to have a
better-looking replacement to cl65's cfg format. That being said, the
end result wasn't *much* prettier either, and the end result could be
even bigger and equally confusing.
Since 5f48de69f46d ("Add support for cfg files") there is quite the
framework in order to support regular cl65's cfg files. Hence, this
commit takes another approach: let's tune this format to a more
compressed and simplified one. This is now the current "nasm cfg"
format, and it allowed us to re-use a lot of code while also being more
to the point for NES/Famicom development than the original cfg format.
With this new format, we can now remove the dependency on TOML and all
of the inner dependencies which were quite a lot.

In order to make tools like `xa65` work seamlessly with existing
configurations, allow this format too instead of making developers
switch to a new file with TOML syntax.

This needed some heavy lifting when it comes to how files were located.
This means that statements like .include/.incbin now take into
consideration a new list made out of SourceInfo, which holds enough
information to translate from which file a node comes from. This has
also been added into errors, so they are more informative on what went
wrong.
In order to tests this, besides all the regular unit tests, a new e2e
test has been added.

This opens up the door for developers to pass their own configuration
files.

This will allow the creation of configuration files that can live
outside of this tree, so developers can fine tune configuration files of
their own without having to pick up whatever is currently available.

Some of the functions are actually private, so don't export them.
Moreover, there was an import cycle which was not needed and was forcing
a public import. Remove that as well.

There was a big missunderstanding on how things were to be laid out in
the end file, and so it was needed to create a proper understanding on
what's a Mapping and what's a Segment. These turned out to be
fundamental concepts that I failed to grok up until this commit.
Hence, this commit re-arranges completely how variables and labels are
stored in the Context, and how these objects can then be translated into
bundles that can be spit out to the caller.
This commit, besides introducing the new Mapping struct, also introduced
a more general Object, which abstracts things from the Bundle struct,
and allows us to pass certain metadata about the bundle at hand.

There were a lot of assumptions on the assembler that stemmed from a
fundamental missunderstanding from my side on how segments are laid out
on the final file. This commit is the first step to address this.

As a way to firstly adapt on the latest changes from the parser since
184c39579227 ("Re-work the parser from scratch"), the assembler had to
leave out some features on 16114b2ca358 ("Adapt the assembler to the
changes on the parser"). This commit reintroduces support for settings
labels, variables and referencing them, while also providing a more
robust implementation at that.

As of 184c39579227 ("Re-work the parser from scratch") the parser has a
proper AST, and the assembler has to traverse it accordingly.
Moreover, the assembler has been stripped from a lot of unneeded memory
allocations and it's overall more keen on using mere references when
possible.

Macros can now be described with the '.macro' control statement, but no
parameters can be given and it's overall pretty brittle.

Procedures are marked with the '.proc' control statement and work both
as a scoping mechanism and as a label that can be referenced.

This is a bare bones implementation of it, and there's a lot of nuance
that it's being missed, but at least the fundamentals have been
implemented already.

Mappings and segments are fundamental blocks on how code is distributed
both on the actual ROM File and in the memory layout.
