This includes some real bugfixes, since it noticed some places we were
being loose with different types!

They're almost entirely autogenerated, and we use symlinks into the
top directory to reduce replication.
They can't be under pyln.spec.message, because a package can't also
be a namespace.
We also add fulltext and desc fields, and exclude our "gen" files from
flake8, since the spec quotes contain weird whitespace.
Changelog-Added: Python: pyln.spec.bolt{1,2,4,7} packages.

This delivers the message contents in a much friendlier form for
manipulation: in particular, it makes it easy to compare two
messages without having to know all the message type internals.

If they don't exist, that's OK. These will eventually be going away
from the spec, but there are still some in gossip messages for now.

Exposing the array types is required for our dummyrunner in the lnprototest suite, since
it wants to be able to generate fake fields.
The set_field is similarly useful.

Other changes along the way:
1. In a couple of places we passed None as a dummy for for
`otherfields` where {} is just as good.
2. Turned bytes into hex for errors.
3. Remove nonsensical (unused) get_tlv_by_number() function from MessageNamespace
4. Renamed unrelated-but-overlapping `field_from_csv` and
`type_from_csv` static methods, since mypy thought they should have
the same type.
5. Unknown tlv fields are placed in dict as strings, not ints, for
type simplicity.

These are autogenerated, but now they export their own
MessageNamespace, as well as the raw csv.
They also expose their SubtypeTypes, MessageTypes and TlvStreamTypes,
though in theory these could clash (they don't for now, and it'd be
kinda awkward if they did).

This contains the CSVs for the current bolts (autogenerated). It's a
separate module because I expect it to be updated alongside the spec.

Changelog-Added: pyln: new module pyln.proto.message.bolts
This will be useful for the next patch, which introduces per-bolt
modules. This makes it easier for them generate variables for each
field type they parse (they don't want to export u16, for example)

Instead of val_to_bin/val_from_bin which deal with bytes, we implement
read and write which use streams. This simplifies the API.

This supports infrasructure for creating messages. In particular, it
can be fed CSV from the spec's `tools/extract-formats.py` and then convert
them all to and from strings and binary formats.
