After 2b2aca1, DictCompiler/Decompiler's `arg_delta` method unconditionally attempts to get the first item to check if it's a list, but this fails with `IndexError` when the value is empty.

We shall reuse it as base class for the _DehintingT2Decompiler in subset module,
as we need to save the width in order to re-insert it after dropping the hints.
- in T2 charstrings, a byte code of 255 is followed by a 16.16 fixed
point number, not a 4-byte int as in T1. Noted by rroberts.
- some integers were not correctly encoded in the T1 compiler.

T{1,2}OutlineExtractor is not backwards compatible and this change
basically makes them private classes: CharStrings now have a .draw()
method that takes a Pen object (see fontTools.pens.*), so you never
have to deal with the extractor objects yourself. Only lightly tested.
