Revert "Default converting to CP-437 and try guess size"
Reverts 2c9a47d224b28cbb51a3ee335fd9970265201b72 as I think the old behaviour works better given PBM font support being kept
Re-add mapping file for CP-437
Automatically use mapping file with same name as image
ex. for "font_6x10.pbm" it will use "font_6x10.txt" in the same directory
