fix: do not skip last char when decompressing text where the last chars are uncompressed

[andipaetzold]

Compressed text is not 100% compressed. It's a mix of compressed and uncompressed text. The compression mode switches between parsing compressed and uncompressed bytes using a 0x00 byte.

There was a bug where the last character was accidentally skipped when it was uncompressed. The root cause was that the number of remaining characters was not calculated correctly and it was assumed that the one char shorter than it actually was.

With this PR, the decompress code should be easier to read and it is more obvious when the curPos variable is incremented. The performance is slightly worse as we read some bytes twice. But I think we can ignore that aspect here.
