Add support for attach a file with metrics information to the font.

Fonts like Type 1, have one file with the glyph image and another
file with metrics and kerning information, this try to search if the font
have this information and load (try open the same file but with the .afm
and .pfm extension).

Also add a function to load the same information from memory, just in case
that in some point we add a font like this.
