This release adds error correction.

• Make Hrp::len function const #212
• Remove unused argument on CheckedHrpstring::fe32_iter #235
• Fix min/max size hint in HrpFe32Iter #253
• Add support for error correction #203 #204 #205
• Alternative fes_to_bytes_zeropad with no dropping of last bits #201
• Derive Default for Fe32 #184
• Introduce a PrintImpl object that can compute various code properties #180
• Add a Hrp constructor from an arbitrary T: Display #196

The 0.10.0 release contains API breaking changes compared to 0.10.0-beta and because of semver rules (which we adhere to) cannot be released with that version number, we had to yank it and re-do the release as 0.11.0 - sorry.

Release the new primitives module! This release is a total re-write of the crate - enjoy.

Right before doing this release we added a few API improvements to the primitives::decode module:

• Add accessor functions to the decode types #167
• Add CheckedHrpstring::fe32_iter function #174
• Make a couple of the functions on CheckedHrpstring struct public #173

Re-implement the crate level API using the new primitives module.

This release introduces a new primitives module that is basically a new implementation of the whole crate. We also add a segwit module but we have not yet settled on the exact new API in lib.rs, hence the alpha release.

<!-- Woops, added to the API in a point release -->

• Support bech32 encoding without a checksum

• Enable edition 2018 bumping MSRV to 1.41.1
• Implement From<u5> for u8
