making posible to handle multiple files extensions with one writer/reader

[Czaki]

handle different variants of extensions in one menu position.
This is my proposition. In my work I meet different variants of tiff extension. On linux, the file chooser hide all files that do not match the pattern. so it can create problems with searching files. Also on linux size of letters has meaning.

Maybe it should be done with some more complicated structure like NamedTuple

import typing 
class FileExtensions(typing.NamedTuple):
	extension_name: str
	extesions_variants: tuple
