This allows the user to run execution until a given address is
reached. This can, like with the --start option, be coupled with the
--nasm option in order to be able to provide an identifier instead of a
regular hexadecimal value.

Allow the --start flag to accept identifiers2026-08-24T14:17:25ZMiquel Sabaté Solàmssola@mssola.com2026-08-24T14:17:25Zurn:sha1:86006af348be75412fdc3dfb5a037b89a01122e8
This is coupled with the new -n/--nasm option, which works in the same
way as in `readrom`.

Add the runrom crate and the vnf library2026-08-17T21:06:23ZMiquel Sabaté Solàmssola@mssola.com2026-08-17T14:03:21Zurn:sha1:df1041d40431251e22e03ec5c4df7fc5767e1543
The vnf library supports the runrom crate and they both combined enable
users to "run" a ROM file. This is basically an emulator, but with two
key differences:
1. It is to be run programatically. That is, you are not expected to
play games with this, but to run code by steps, start at a given
address, run a function, etc.
2. It is headless: there are no graphics displayed on screen, nor sound
being delivered.
Thus, the target for both these things are developers, not players. This
way developers can validate code paths without needing a full blown
emulator. You can write tests with this and be able to run some checks
as part of your testing infrastructure.
