Release TileJSON v3 support, bounds, and center structs

Note that this GitHub release catches up to what has been release to crates.io

ATTENTION: This release contains many breaking changes. See README for usage examples.

v0.3.2 (2022-10-30)

• Add Bounds::from for [f64; 4], [f32; 4], [i32; 4]
• Add Bounds::try_from now also supports &[f64], &[f32], &[i32] in addition to Vec<f64>

v0.3.1 (2022-05-29)

• Add Bounds::MAX to create a maximum -180..180, -90..90 value.
• Add Bounds::MAX_TILED to create a maximum allowed for vector tiles per spec.
• Implement Add and AddAssign on Bounds

v0.3.0 (2022-05-25)

• Migrate to Rust 2021 edition
• update docs to match v3.0.0 spec
• add fillzoom field per v3.0.0 spec
• add Center and Bounds structs instead of arrays
  • both support FromStr trait
• add VectorLayer struct and the vector_layer field
• Remove builder pattern because TileJSON is writable
• Add other fields for any unknown fields in root and vector layers
• Restructure instantiation:
  • use tilejson!{ source } macro to create TileJSON objects, with any number of the optional field: value pairs.
  • use set_missing_defaults() to replace all missing values with their defaults (only if the spec defines it)
• Remove id field because it is not supported by the spec
