**Is your feature request related to a problem? Please describe.**

It would just be a nice add-on

**Describe the solution you'd like**

It would be cool to have an icon for **Assembly** languages for `nvim-web-devicons` and `exa` to use

**Describe alternatives you've considered**

I don't know any other solution

**Additional context**

There is no icon nor mascot for Assembly `.asm` files in general, but Netwide Assembler is quite popular and with its icon could fit that spot
