Should seqStartOffset be added to SEEK_SET?

[m-7761]

Adapting this code to read from a T archive (a PlayStation thing) the input FILE needs to be rewound to its first sector instead of the top of the file:

seq2mid/src/seq2mid/seq2mid.c

Lines 69 to 73 in c8597af

	fseek(fSEQp, 0x14, SEEK_SET);
	}
	else
	{
	fseek(fSEQp, 0x0F, SEEK_SET);

seqStartOffset is already handy, maybe it should be added if appropriate?

seq2mid/src/seq2mid/seq2mid.c

Line 50 in c8597af

seqStartOffset = (int) ftell(fSEQp);
