ArcDPS bindings v0.13.0

This update includes large scale reworks & restructuring. Migrating will likely require manually updating code to work with the new interface.

• Rename arcdps_evtc to evtc and arcdps_parse to evtc_parse.
• arcdps now has the "unwind" feature enabled by default.
• Add new CLI tool evtc_dump.
• Showcase all callbacks in arcdps_example_plugin.
• Event, arcdps::evtc::Agent and other structs are now equivalent to their raw C version. Fields may be accessed as Rust types via struct methods like Event::get_statechange.
• Events can be categorized as EventCategory.
• Events can be converted into EventKind, a Rust-like enum representation of events.
• Add Rust-like struct equivalents for every kind of EVTC event, for example BuffDamageEvent.
• Add traits evtc::TryExtract and evtc::extract::Extract for converting EVTC events into their Rust-like equivalent.
• Rename evtc_parse::Agent's address field to id to be in line with other uses.
