Support formatting files with extensions other than .asm

[bernborgess]

For organization purposes, many files that contain x86 assembly don't use the format .asm, but rather .s or .x86 and so on. However, when using VSCode to format such files with Ctrl+Shift+P > Format asm
it errors with message "You can only format .asm files".

Do you think we should enable other file formats? If so, I'd be looking into such feature and submitting a PR, depending on the answer. Thanks for the formatter, btw!

If you want to make a PR I'm fine with that

@bernborgess I built on this project and published an extension that supports .asm, .s, .mips, and .spim, along with some other formatting improvements (comment alignment, data section alignment, format-disable regions, etc.).

It's not a direct fork so I can't PR it back cleanly, but it should solve this issue if anyone needs it. I thought this repo was abandoned and didn't realize @NotAFlyingGoose was still alive 😅so didn't exactly fork it sorry about that
