`databarexpandedstackedcomposite` doesn't escape characters correctly with `parse` about postscriptbarcode HOT 2 CLOSED

For composite symbols, multiple helper encoders are called that are passed the same instance of the options dictionary, which they modify (for example by clearing parse) before calling the ultimate encoder. However, these changes unintentionally bubble back up to the caller and therefore erroneously affect subsequent encoder calls.

I've fixed obvious issues by avoiding superfluous modifications to the options dict. I may have missed some instances in which case the generic (but less efficient) fix is of the form presented in 4e13013.

Please test and if it looks good I'll cut a new release.
