Update to rust-lightning:0.0.117

The highlight in terms of code changes in `rust-dlc` is:

Use new LDK Channel ID struct
=============================

Start to use newly introduced `ChannelId` struct. With a stronger type
we are less likely to mix up LN `ChannelId`s, DLC channel IDs and
contract IDs. To that end, we've renamed the old `ChannelId` type
alias to `DlcChannelId` since it is now only supposed to be used
for (temporary or final) DLC channel IDs. We should consider
introducing a struct at some point.

To ensure backwards-compatibility we're still serialising the LN
channel IDs into bytes, but we now have to use the `serialize_with`
attribute since LDK's `ChannelId` doesn't implement serde itself. The
same applies to deserialisation.
