Subject: [PATCH] Fixed a bug that could cause negative
 general_profile_compatibility hex value to be returned

Bug: if general_profile_compatibility negative after reverse, then decimalToHex() returns negative hex value and mime codec, generated by test/node/mp4codec.js will be wrong. This commit fixes this.
