Fix no_std build failure and raise mininum Rust version

This release resolves build failures for no_std configurations and raises the minimum required Rust version to 1.67.1.

Thanks to @AkiyukiOkayasu for providing the patches!

Fix an OSC decoding issue

This fixes a bug 🐛 with decoding OSC strings whose contents, excluding the null termination byte, were four-byte aligned.
Clients are recommended to update to this version. See #51 for details.

Thanks to @edjin for providing the initial patch.

TCP encoder and usage examples

See #50 for details.

Note Version v0.11.2 on crates.io got accidentally published from a feature branch.

Implement std::fmt::Display for all OSC types

This includes #53 that implemented std::fmt::Display for all OSC types.

Rust Edition 2021

This updates the crate to follow Rust Edition 2021.
Rust 1.56 is now the minimal required version.

Better docs

This release just adds some additional context to the decoder::decode_tcp docs and fixes some link in other doc strings. Without a release the new doc strings would not show up on https://docs.rs/rosc.

Improved Encoder API

Thanks to @Barinzaya for submitting #44 which improves the encoder API in two ways:

1. It defines a new Output trait and a new encode_into function that allows to encode OSC data into anything that implements the Output trait. The Output trait got implemented of Vec<u8>, so that the existing encode function can leverage encode_into under the hood.
2. Encoder performance improved by an order of magnitude 🚀 🐎 ! There was no regression, only speedups between 5 and 21 times. This was mainly achieved by preventing a lot of allocations (as done in the previous implementations). For more details see #44.

Apply clippy suggestions

This is a housekeeping release that implements clippy suggestions from #43 and #42.

Minor enhancements

With this release the Display trait get's implemented for OscAddress (08b2d4f) and a number of other address related structs now derive Clone and Debug traits.

Use String to store OSCAddress

We now use String to store an OSCAddress because it will prevent lifetime issues when the given address does not live long enough. Thanks again to @DrLuke for this fix 🎉 !
