[Bug] Some Sysiphus discs cause BoS to hang

[HeroponRikiBestest]

Some Sysiphus discs cause BoS to hang due to ring protection resulting in 0x55 that's interpreted as a giant string of 'U', causing pex.overlays to hang forever.

Implementation notes:

• Will need to be updated in Serialization
• A reasonable cap value for repeated characters needs to be established before it's thrown out (64)

[mnadareski]

Any string of a single character 64 times will now be discarded in Serialization: SabreTools/SabreTools.Serialization@700b035

This has not been updated in BOS yet, so this item will remain open until then.
