fix: better file type detection

[oskarrrrrrr]

Fixes missing highlighting for some file types (e.g. typescript or bash).

Fixes: #122

[oskarrrrrrr]

Are we okay with the dependency?

[dmtrKovalenko]

Actually not sure about it I think for such a simple function maybe we can just copy the code from plenary sources?

[oskarrrrrrr]

Copied the minimum amount of code that does what we want. Removed detecting based on shebang and modeline because I don't think that they're too important (also I would have to copy/reimplement more code for handling files).

I still feel like it's a lot for such a simple feature. We could put the file from data folder inline in filetype.lua and simplify logic a bit. Should I do that?
