Consolidating multiple issues here:

• blacklist BED file with one entry #196
• bg2 file with a header #128
• malformed pairs file #135
• spaces instead of tabs in chromsizes file #124
• other chromsizes weirdness #142

This class is nice. I may worth to move this in libzim's tools and use it everywhere we create a stringstream in our code.
This could even be merged with a to_string function.

Describe the bug
Method Decompress() at ARM9.java does this:

public static byte[] Decompress(byte[] Data, int _start_ModuleParamsOffset)
	{
		if (IOUtil.ReadU32LE(Data, _start_ModuleParamsOffset + 0x14) == 0) 
			return Data;//Not Compressed!
		
		byte[] Result = CRT0.MIi_UncompressBackward(Data);
		IOUtil.WriteU32LE(Result, _start_ModuleParamsOffset + 0x14, 0); //sets 4 byt
