[ttProgram] don't write empty <assembly> or <bytecode> elements 
That means that, when reading from XML, we fallback to empty lists in case 'assembly' or 'bytecode' attrs are not there.

bec499ac05 Indent XML output for TT assembly instructions 
Indentation for TTX XMLF is 2 spaces. I chose 4 spaces for indentation of instructions to make it more noticeable. I hope it’s not a problem, because assembly code lines are usually very short.

a36c74e8b8 Add logic for keeping PUSHB/PUSHW distinction 
And avoid merging consequent pushes.  No option to control this
externally right now, but the logic is there.

965c87fb4a When disassembling, merge multiple PUSH ops 
Fonts typically have multiple consecutive PUSHB / PUSHW
operators.  Merge them in the disassembled output.

This, for now, generates worse assmebly because all PUSHB's
grouped with PUSHW's now generate as PUSHW.  Followup fix
will address that.

ce84d3215e Generate PUSH mnemonic for PUSHB/NPUSHB/PUSHW/NPUSHW 
Reduces XML noise while reenabling the optimization
during assembly.

3714c78c92 When writing PUSH instructions, obey requested opcode 
Previously fonttools was choosing between the optimal opcode
from PUSHB, NPUSHB, PUSHW, and NPUSHW.  We now respect
whatever was requested and err if the format doesn't support
the data.

Morevoer, if the number of numbers to push is more than 255,
we add multiple push instructions to push all the numbers.

Finally, add a new pseudo-opcode "PUSH" that automatically
chooses the best format.

This, by itself, reduces roundtrip noise by not optimizing
the bytecode as it was before.  In a followup commit I'll
change the bytecode disassembler to always produce PUSH
in the textual instructions instead of the four variants.
That way, we get both the optimization during assembling,
and reduced noise in XML.

fc4f438496 Fix parsing of hinting instructions that end in a PUSHB 
Sounds useless, but MReifutaiM-Regular.ttf seems to have that, and the
parsing back from XML was failing because we expected a token whereas
after dropping whitespace there wasn't any left.
