Search all faces in file #77
Description
Currently, it looks like FreeTypeAbstraction only searches the first face in each file, as can be seen here.

Line 143 in b7d6d65
try_load only loads the face at index 0 - we should load all faces, and loop through them internally.
We can get the number of faces in a file by this operation.
