UTF-16 files detected as MP3 due to frame sync check

[MadafakinRio]

Hey, I ran into an issue with this line of code while scanning my music folder.

TagLibSharp2/src/TagLibSharp2/Core/MediaFile.cs

Line 300 in 357e28c

if (data.Length >= 2 && data[0] == 0xFF && (data[1] & 0xE0) == 0xE0)

This condition also matches some non-MP3 files.

For example, desktop.ini files on Windows are often encoded as UTF-16 LE and start with the byte order mark FF FE.
Since 0xFE & 0xE0 == 0xE0, the check evaluates to true and the file is detected as MP3.

So any UTF-16 LE text file could potentially trigger this.

Maybe the MP3 detection could validate additional header bits to avoid false positives.

Thanks for the library
