[Backport release/3.13] FAST: cap band count at MAX_FILES when parsing BANDS PRESENT (#14913)

For IRS P6 datasets the BANDS PRESENT loop in FASTDataset::Open() opened one channel per digit and incremented l_nBands without checking it against MAX_FILES (7), the size of the fpChannels/apoChannelFilenames member arrays. BANDS PRESENT holds up to 32 chars and a repeated digit reopens the same sidecar each time, so l_nBands walked past the arrays and OpenChannel() wrote out of bounds. Cap it at MAX_FILES, like the FILENAME fallback loop's i<7 bound.
