dotcode: handle Shift B CRLF in encC and encA

[gitlost]

Handles CRLF when doing Shift B in Code Set C or A, otherwise e.g. 10 100 moveto (12a^013^010) (parse) /dotcode /uk.co.terryburton.bwipp findresource exec and 10 100 moveto (^001a^009^013^010) (parse) /dotcode /uk.co.terryburton.bwipp findresource exec will fail.
