fix: limit max upload size (#224)

Adds limit based on previous decisions, considering that S3 Put command
has hard-limit of 5GiB.

- By limiting CAR size to 127*(1<<25), we guarantee max-4GiB-padded
Filecoin pieces and have better utilization of Fil sector space.
- By receiving one more byte, we would immediatly get to 8GiB padded
piece.

Closes storacha/w3up#827
