release v1.0.0

[rursprung]

pre-requisites:

• roadmap to v1.0.0? knurling-rs/defmt#795
• Version 1.0? kornelski/rust-rgb#39
• ensure that we fulfill everything from the API checklist, at least these seem to be wrong or at least need to be double-checked:
  • Feature names are free of placeholder words (C-FEATURE): we currently have use-alloc and use-heapless - we need to drop the use- prefix
  • Types eagerly implement common traits (C-COMMON-TRAITS) - to be double-checked
  • Error types are meaningful and well-behaved (C-GOOD-ERR) - should probably be implemented for std environments?
  • Crate level docs are thorough and include examples (C-CRATE-DOC) - missing explicit example for calling the library directly in the rustdoc & readme
  • Public dependencies of a stable crate are stable (C-STABLE) - see dependency list above, they're all at 0.x 🙁

update: the heapless dependency is now gone since #38 and the same is true for the use-[alloc|heapless] features (and other things have been fixed as well)
