Remove naia-parse, improve naia-serde/naia-derive, add TickManagerConfig

[cBournhonesque]

Hi,

I was intending this change to primarily be about derive-stuff, but it seems like some other changes got looped in. I struggled a little bit with the merge conflicts as there was a lot of stuff! (the main branch I operate on is still on naia 0.14) There might still be some errors related to the merge

Changes

Main change:

• remove naia-parse

  • modernize naia-derive for ChannelIndex(stop using naia-parse)
  • modernize naia-serde (stop using naia-parse). I would also suggest to rename the Serde trait, it can be somewhat confusing when users already have the serde crate imported somewhere.
  • In particular, #[derive_channels] and #[derive_serde] have been replaced with #[derive(ChannelIndex)] and #[derive(Serde)]. I think this change is much cleaner and benefitial in the long-term. I've been annoyed a couple times by the previous behaviour where #[derive_serde] would derive PartialEq and Clone without me being aware of it (and was preventing me from deriving it explicitly)

  Additional small changes from previous PRs:

  • added a has_entity method on the bevy server (was useful for me to update scopes)

  • added a TickManagerConfig object to make the client's tick manager more configurable. I had to experiment a lot with the tick manager, updating the jitter buffer, etc. I think this is definitely needed.

  • expose some methods to access the client_receiving_tick and client_sending_tick

Migration guide

• Replace any use naia_serde::derive_serde; with use naia_serde::Serde;
• Replace any #[derive_channels] with #[derive(ChannelIndex)] (should probably also make the other derives explicit here..)
• Replace any #[derive_serde] with #[derive(Clone, PartialEq, Serde)]

Beautiful :pray: Yeah this stuff has changed a lot for the 0.16 release too, thank you very much though for this, I will be able to integrate it into the 0.16 release, great stuff :+1:

• I successfully integrated your Derive / Parse changes in https://github.com/naia-lib/naia/pull/137, thank you again :pray:
• As far as the TickManagerConfig stuff ... I'm going to need to wait on that a bit, I appreciate it though!

I got this ported over to Release 0.16 at https://github.com/naia-lib/naia/pull/137, thanks again Charles! :pray:
