The kind of alignment that cbfstool seeks is, for alignment "ALIGN",
look for an address so that the file data is inside a block sized ALIGN,
aligned to ALIGN granularity, with enough space before it so that the
header fits.

So if you look for a suitable location for a file of 99192 bytes, that
has to be inside a 0x80000 block, aligned to 0x80000, 0xf380 is okay:

The block in question starts at 0x0 and ends at 0x7ffff.
The file starts at 0xf380, and ends at 0x276f8.

We have a less strict requirement than the one you assumed (that the
file must start at the beginning of such a block)
