Try to get context from the moov atom when the hoov before moov atom,
because the streams info get a possible incorrect when there have both
hoov and moov atom. So add and ignore_hoov option for try to get
moov context by user.

TBH, add an option is too much effort to workaround such broken files. I prefer
a.type == MKTAG('h','o','o','v') && c->fc->strict_std_compliance < FF_COMPLIANCE_UNOFFICIAL
But it will break those samples if user doesn't lower strict_std_compliance.

No by default. And Yes if have both hoov and moov.
Yes it should break if user use ignore_hoov option.
Add ignore_hoov can be choosed by users.
