Everything is an Event::Start with utf-16 files

[bbergeron0]

I have several UTF-16 files which doesn't parse properly.

When looping with read_event_into, most stuff gets interpreted as a tag start, including comments, self-closing tags, CDATA, and closing tags.

OS: Gentoo Linux
quick-xml version: "0.27", no additional feature flags
Input XML: These files are Skyrim "FOMod" files used for modding. This archive contains an UTF-16 encoded XML file named "EnhancedLightsandFX 3.06/fomod/ModuleConfig.xml" which doesn't parse properly with quick-xml.

Unfortunately only single byte encodings are supported at the moment https://github.com/tafia/quick-xml/blob/master/src/encoding.rs#L31

The work to eventually enable it is tracked here #158, I will close this issue as a duplicate.

I have a PR where I got it working in limited scenarios, however, I was roadblocked by the difficulty of async support and my free time mostly drying up for a few months. I'll pick it back up once I have time again.
