Naming conflict between CryptoSwift's Data.bytes and Foundation's new Data.bytes property

[CrazyFanFan]

In CryptoSwift/Sources/CryptoSwift/Foundation/Data+Extension.swift, the extension on Data defines:
public var bytes: Array<UInt8>, which conflicts in naming with the newly added property in Foundation:
var bytes: RawSpan { get }.

Either we can rename the extension, or make it use the new Foundation property directly if it matches enough. It needs diving deeper.

Fixed in #1076. Obviously this is a breaking change though.

Yes, but I don't think we can do anything working with Swift 6.2 which is not breaking change. I updated the README accordingly for Swift 6.2 support with versions and branches.
