/**
* The file server has a file size limit of `maxFileSize`, which the Service Nodes try to enforce as well. However, the limit applied by the Service Nodes
* is on the **HTTP request** and not the actual file size. Because the file server expects the file data to be base 64 encoded, the size of the HTTP
* request for a given file will be at least `ceil(n / 3) * 4` bytes, where n is the file size in bytes. This is the minimum size because there might also
* be other parameters in the request. On average the multiplier appears to be about 1.5, so when checking whether the file will exceed the file size limit when
* uploading a file we just divide the size of the file by this number. The alternative would be to actually check the size of the HTTP request but that's only
* possible after proof of work has been calculated and the onion request encryption has happened, which takes several seconds.
