ToHex shouldn't require padding between bytes.
...
This was getting obnoxious for SHA-1s, and particularly so when serving them
as etags.

Logic for generating .mp4 virtual files.
...
This is still pretty rough. For example, there's no test coverage of virtual
files based on multiple recordings. The etag and last modified code are stubs.
And various other conditions aren't tested at all. But it does appear to work
in a test that does a round-trip from a .mp4 file, so it should be a decent
starting point.

Compute the full AVCSampleEntry (avc1 box).
...
This code isn't pretty exactly---particularly the hardcoded lengths---but it
does work. I'll have a different mechanism for calculating the length and
nesting structure forthe more dynamic parts of the moov atom. This way is
convenient when generating a single string of mostly static data.
