Unable to use py-ios-device on m1 mac

[kandji-joel]

When installing via poetry, cryptography==3.3.2 (which is required by py-ios-device) fails to install on m1 mac. I can install on intel mac without problem. It looks like the m1 mac is trying to install 37.0.2 of cryptography

@YueChen-C any thoughts on this?

[YueChen-C]

I think we can delete the cryptography dependence, because pyOpenSSL will install the latest Cryptography (cryptography>=35.0)

Thanks @YueChen-C -- I confirmed this fixes the install issue, however when using the package on m1 mac I'm seeing more errors that do not occur in the same environment on an intel mac -- I can log a separate issue for this

(my colleague has the m1 mac, mine is intel -- I will confirm with them next week if solution above resolves the issue)
