Added support for filtering by multiple filetypes and extensions

#177 #199

Changes

You can now specify multiple extension and file type filters by simply adding more -e or -t options, respectively, as was suggested in the above issues.

So, to find all files and symlinks with the extension .c or .h, you could run

fd -ec -eh -tf -tl

@tkadur Welcome and thank you very much for your contribution!

It would be great if we could also:

• Update the tests (add a tests for multiple file types and for multiple file extensions)
• Update the long --help text (describe what happens if multiple options are specified)
• Update the man page in the same way.

Also, there seems to be a problem with additional pattern matching.

With this PR:

▶ touch test.txt
▶ fd -e txt foo
test.txt

Previously:

▶ fd -e txt foo

(no match)

Thanks!

I updated the help text and tests and also fixed the issue you mentioned. I'm not quite sure what you mean by updating the man page though.

Thank you very much!

The man page is the file in doc/fd.1 - I'll simply update this later before releasing the next version.
