Cleanup: pass EqualityOptions as const&

This exposes a useless assignment of export_differing_subtitles, which I've removed (and altered the comment accordingly).

Some more detailed notes in dcpdiff.

Remove and from tags.

They should not be there: "EntryPoint" ... "This element shall only be present when the Asset refers to an external resource such as a Track File". Fixes DoM bug #2215.

Use optional for ReelAsset _annotation_text.

Not only is this tag optional in Interop and SMPTE, but it would appear that if it is present but empty a DCP will not play back on Sony SRX320 / LMT3000 systems (DoM bug #2124). Here we use optional<>, as seems to make sense, and also refuse to write empty tags (instead omitting the tag entirely).

Fix/hide some warnings.

Tidying.
