version bump 0.7.5: more performance

Browse Source 
- eliminated functional constructs in hot functions
- format try-catch block extracted into new function
- cpexcel + codepage updated to 1.2.0
- more efficient (and correct) clean implementation of RGB/HSL/tint algorithms
- xlsx binary --all option enables every extra formatting and saving option
- column widths parsed and saved (requires cellStyles:true)
