Remove support for dose

Browse Source 
Since there isn't GDS/OASIS level support for dose, this can be mostly
handled by using arbitrary layers/dtypes directly. Dose scaling isn't
handled as nicely that way, but it corresponds more directly to what
gets written to file.

Masque is a Python module for designing lithography masks.
The general idea is to implement something resembling the GDSII file-format, but
with some vectorized element types (eg. circles, not just polygons), better support for
E-beam doses, and the ability to output to multiple formats.
