Add support for other font tables used for color glyphs

Althrough we have already got support for 'SVG ' table from OpenType fonts, there are some other font tables used for color glyphs. These tables includes:

COLR 	Color table
CPAL 	Color palette table
CBDT 	Color bitmap data
CBLC 	Color bitmap location data
sbix 	Standard bitmap graphics

Since they are documented in the OpenType specification, it’s resonable to add support for them to import color glyphs into document.
