* usb: unify handling of length parameters
The length parameters in USB packets are strict and the existing
implementation does already hardcode the length within the serialize
functions. Therefore the user should not provide these lengths during
creation time. In order to make this more verbose use defaults values
within the structs and reference these defaults values within the
serialization functions. It's not possible to remove these fields
completly as this fields are used within deserialization from the
hardware itself.

* Remove length fields as they are obsolete. The lengths is only required
during the serialization and therefore is already hardcoded. The only
other convinience is the calculation of the descriptor size, but this is
already wrong. extern structs are padded and therefore do not have the
right sizes.

This field is a bit tricky: It belongs to the EXECCTRL register, while
most of the other fields can determined based on the directives used in
the assembled program, this one has to be set explicitly. This makes it
so that we have to plumb some way to explicitly set the field. I did
this by making `LoadAndStartProgramOptions` take `ExecOptions`, but this
isn't perfect, because if a user sets other fields, they will be ignored
in favour of the values set in the program.
* Adds better docs to README.md
* Adds tar, gzip to bundle.py checked dependencies.
* Adds fancy rendering of .data/chip-families.svg in output for embedding.
