[Bug] RomM gets stuck while triying to scan some roms (.7z extension related)

[outerwinnie]

RomM version 3.5.1

Describe the bug It seems that if a rom have .7z extension and goes over certain size, RomM gets permanently stuck scanning that one rom.

To Reproduce Steps to reproduce the behavior:

1. Scan a rom file with .7z and over 4Gb (maybe 3Gb)
2. See error

Expected behavior It shouldn't get stuck there, and should identify the rom correctly as (i think) was pre 3.5.0
