chroma/lexers/i/io.go
Alec Thomas 563aadc53c Moved lexers into alphabetical sub-packages.
This was done to speed up incremental compilation when working on
lexers. That is, modifying a single lexer will no longer require
recompiling all lexers.

This is a (slightly) backwards breaking change in that lexers are no
longer exported directly in the lexers package. The registry API is
"aliased" at the old location.
