`sgxs-tools` failed to compile when using feature `pe2sgxs` on `nightly`

[Taowyoo]

This is because dependency is failed to compile because of recent update of rust nightly:

make unaligned_reference a hard error #102513

The dependency jethrogb/pe-rs need to update to fix this.

Created corresponding issue in pe-rs : jethrogb/pe-rs#6

[Taowyoo]

Found this error from recent PR: #432

[jethrogb]

Can we please fix this ASAP as we are no longer able to test on stable

Pls check PR jethrogb/pe-rs#7
