dft instructions file parser

description

this lib/bin project is the official tool to parse, lint and fix .dft files

why

while working in the dft project I realized 2 things:

• the dft tool itself shouldn't be responsible of parsing the instructions file, but rather the execution itself

• haven't made a parser yet, so... here's one

grammar (BNF)
