Subject: [PATCH] Fix ytInitialData parsing

For some reason Ruby and Crystal add PCRE_DOTALL to the "m" flag which
is supposed to be PCRE_MULTILINE. I guess that makes sense, but it's
nonstandard and I had to read the Crystal source to figure it out.
See https://github.com/crystal-lang/crystal/blob/4c88b8b69babbcb877169f3e3b9dcf1d9ff189a0/src/regex/regex.cr#L10
