Currently, cbfstool prints the following error message when the added
file doesn't fit in the region:
E: Could not add [file, 1024 bytes (1 KB)@0x0]; too big?
It requires manual inspection to know the space left in the region. To
make that easier, also print the maximum empty CBFS entry size in the
error message:
E: Could not add file [header 76 + content 1024 bytes (1 KB)] @0x0;
Largest empty slot: 512 bytes
