Infinite loop with certain input files

Hi! First, thanks a lot for your library! I appreciate it very much that you made it available to everyone.

I ran detection on a bunch of files and found that the following ones cause an infinite loop.

MP3

File: https://github.com/WebKit/WebKit/blob/6cf28a29e81644f42c8bffff78f410003df87ec6/LayoutTests/imported/w3c/web-platform-tests/mimesniff/media/resources/mp3-with-id3.mp3

Infinite loop:

audio_metadata_reader/lib/src/utils/buffer.dart

Line 52 in 68b0915

while (filled < size) {

Infinite loop:

audio_metadata_reader/lib/src/parsers/ogg.dart

Line 82 in 68b0915

while (page?.headerType != 0x04) {

Maybe WebKit chose some particularly interesting audio files for their tests ;)
