v0.11.0

• Bumped minimum Go version to 1.17.
• Switched from /r0 to /v3 paths everywhere.
  • The new v3 paths are implemented since Synapse 1.48, Dendrite 0.6.5, and Conduit 0.4.0. Servers older than these are no longer supported.
• Switched from blackfriday to goldmark for markdown parsing in the format module and added spoiler syntax.
• Added EncryptInPlace and DecryptInPlace methods for attachment encryption. In most cases the plain/ciphertext is not necessary after en/decryption, so the old Encrypt and Decrypt are deprecated.
• Added wrapper for /rooms/.../aliases.
• Added utility for adding/removing emoji variation selectors to match recommendations on reactions in Matrix.
• Added support for async media uploads (MSC2246).
• Added automatic sleep when receiving 429 error (thanks to @ownaginatious in #44).
• Added support for parsing spec version numbers from the /versions endpoint.
• Removed unstable prefixed constant used for appservice login.
• Fixed URL encoding not working correctly in some cases.
