Font subsetting and font optimization improvements (#362) ...

* Track runes in IdentityEncoder (for subsetting), track decoded runes

* Working with the identity encoder in font_composite.go

* Add GetFilterArray to multi encoder.  Add comments.

* Add NewFromContents constructor to extractor only requiring contents and resources

* golint fixes

* Optimizer compress streams - improved detection of raw streams

* Optimize - CleanContentStream optimizer that removes redundant operands

* WIP Optimize - clean fonts

Will support both font file reduction and subsetting. (WIP)

* Optimize - image processing - try combined DCT and Flate

* Update options.go

* Update optimizer.go

* Create utils.go for optimize with common methods needed for optimization

* Optimizer - add font subsetting method

Covers XObject Forms, annotaitons etc.  Uses extractor package to extract text marks covering what fonts and glyphs are used.  Package truetype used for subsetting.

* Add some comments

* Fix cmap parsing rune conversion

* Error checking for extractor.  Add some comments.

* Update Jenkinsfile

* Update modules
