487facf1f0 pyln-client/gossmap: more fixes, make mypy happier.
Mainly fixing type annotations, but some real fixes:

1. GossmapHalfchannel.from_str() should be a classmethod.
2. update_channel had weird, unusable default values (fields can't be NULL,
   since we use it below).

[ There was one more occurence where isinstance should be used above
type() == xyz comparison. -- MS ]

ba2bcac530 pyln-client/gossmap: Don't mix bytes and GossmapNodeId
Do not mix bytes and GossmapNodeId when accessing Gossmap.nodes dicts.

Therefore the definion got GossmapNodeId also needed to be pulled to the
beginning of the file.

b6ed405d8c pyln-client/gossmap: adds channel satoshi capacity
This reads the `gossip_store_channel_amount` that always follows the
`channel_announcement` messages. Therefore it uses an internal variable
_last_scid to know what channel has been added last time.

75126a0997 pyln-client/gossmap: add NodeId class.
This is more efficient than converting them all to Pubkeys: about 3.8
seconds vs 5.4 seconds.  Usually treating them as raw bytes is what we
want anyway.

e495462c50 pyln-client/gossmap: save deconstructed fields instead of raw msg bytes.
We have to parse them anyway, so why not make them accessible.

1a5a26d659 pyln.client: new functionality to access Gossmap.
It doesn't do much work, but it does parse the gossmap file and extract
nodes and channels.
