midx.c: prevent overflow in `write_midx_internal()`
When writing a MIDX, we use the chunk-format API to write out each
individual chunk of the MIDX. Each chunk of the MIDX is tracked via a
call to `add_chunk()`, along with the expected size of that chunk.
Guard against overflow when dealing with a MIDX with a large number of
entries (and consequently, large chunks within the MIDX file itself) to
avoid corrupting the contents of the MIDX itself.
