0.12.0

This release adds a few new features:

• New charactersEscapedInAttributes and charactersEscapedInElements properties on XMLEncoder that allow customizing how certain characters are escaped.
• You can now override the implementation of TopLevelEncoder Combine protocol conformance when subclassing XMLEncoder.
• New prettyPrintIndentation property on XMLEncoder, which can take XMLEncoder.PrettyPrintIndentation values such as .tabs(1) or .spaces(2).

Thanks to Kenta Kubo for the contribution!
