Remove exceptions

[p0nce]

For Hipreme Engine would probably help

• [x] encoding functions return a isError flag
• [x] read function use the isError flag
• [x] OPUS is devoid of throw
• [x] in OPUS decoder, seek error is handled (well, all but one)
• [x] in OGG, skip should be able to fail
• [x] WAV encode is devoid of throw and checks writes
• [x] WAV decode is devoid of throw
• [x] QOA finalizeEncoding should report write errors
• [x] Initialization functions do not throw anymore, and use isError only (BREAKING!!!!)
• [x] Everything is nothrow @nogc in audioformats

Tag audio-formats v3.0.0 since API changes (isError instead of Exceptions). Is isError then the stream is corrupted and unusable until recreation.
