  -----------
  Enable CoolKey driver to handle 2048-bit keys.

For a problem description, see <https://github.com/OpenSC/OpenSC/issues/1524>.
In a nutshell, for a card with the CoolKey applet and 2048-bit keys,
the command
	pkcs11-tool --test --login
fails to complete all of its tests.

This commit consists of a patch from @dengert.

To avoid triggering an error when the data exceeds 255 bytes, this commit
limits the amount of the payload sent to the CoolKey applet on the card based
on the maximum amount of data that the card can receive, and overhead bytes
(namely, a header and nonce) that accompany the payload.

With this change, the command
	pkcs11-tool --test --login
succeeds.
