Disable unsupported SHA-2 pubkey algorithms (#67)

As documented in paramiko/paramiko#1961 there is an incompatibility between Paramiko 2.9+ and dropbear (the SSH server used on Remarkable) when negotiating the pubkey algorithm. This fixes the issue by disabling SHA-2 algorithms, causing Paramiko to offer a SHA-1 algorithm which Dropbear will accept.
