Problem with huge files

Crash occurs when the target file was not fit into the memory:

TheInternetBackup.com Zone Submission CLI tool, version 1.0.0

✓ Authenticated to TheInternetBackup API successfully.


#
# Fatal error in , line 0
# API fatal error handler returned after process out of memory
#

And there is also problem with submitting files large than 4GB:

TheInternetBackup.com Zone Submission CLI tool, version 1.0.0

Start in tib-cli.js at upload_domain_list around line 118 and follow its call from line 66. Reproduce the failure with a file that exceeds available memory and with a file larger than 4GB; done means both uploads complete without the out-of-memory crash or the Buffer.allocUnsafe size error.
