Case insensitive matching.

[JustinAzoff]

It would be useful if there was a way to match strings ignoring case. It would likely be fine if the case was ignored at create time, like.

local p = paraglob_init_ignore_case(pats);

or maybe

local p = paraglob_init_with_flags(pats, PARAGLOB_IGNORE_CASE);

or similar for

paraglob_match_ignore_case(...);

Currently one can accomplish this by initializing patterns with lowercase strings and use

paraglob_match(p, to_lower(some_string));

but that has a large overhead.
