off-by-1: previously, hybiframes with a 65536 bytes payload
would generate a 16 bit size header signaling 0 bytes (pack("n", 65536) => "\x00\x00"),
instead of using a 64bit size header.
nit: composer.json php version had not been updated since 8.0.2
nit: instead of is_int && in_array, we can use in_array's strict mode.
nit: $this->offset_mask and $this->offset_payload were
initialized-to-null in constructor and encode, then written internally in getPayloadOffset,
then written in encode() again.
nit: use pack('J') instead of manually constructing big_endian_u64 (undocumented funfact, J is not available in 32bit php: php/doc-en#4644 ,
that may be why the original code did not use J)
nit: use random_bytes instead of openssl_random_pseudo_bytes(),
the original code was written for php5 where random_bytes did not exist.
nit: getInitialLength() was calculating the result twice internally.

(but I don't wanna say "64bit formats are not available in 32bit" because d, e, E, the float64 formats are available in 32bit builds, contrary to what the php-src error message suggest.)
