add options to disable some snippents

[TheRealSyler]

i wanted to add options to disable some snippets so that they don't fill my suggestions, then after doing npm i i realized that this repo is not the entire source code, thats why im opening this issue, it would be nice if you could add options to disable snippets by file type, its probably not a huge time investment and it would really help me because i only use the html snippets, if you send me the source code i can also do it as i said its not complicated.
