[pkcs11-tool] --slot parameter expects ID in decimal form

[metsma]

Problem Description

pkcs11-tool --slot parameter expects ID in decimal format and --list-slots parameter prints slots in hex format.

Proposed Resolution

Specify that it excpects slot ID in decimal format or modify code to accept hex format.

Steps to reproduce

pkcs11-tool -L
Available slots:
Slot 0 (0x0): SafeNet Token JC
...
Slot 8 (0x10): 
...
pkcs11-tool -O --slot=10
error: PKCS11 function C_OpenSession failed: rv = CKR_SLOT_ID_INVALID (0x3)
Aborting.
pkcs11-tool -O --slot=16
Using slot with index 8 (0x10)
...

It should really be enough to use what pkcs11-tool -L lists in the brackets, i.e pkcs11-tool -O --slot=0x10

Oh I did not know, 0x10 works. Maybe then parameter documentation should be clarified.
I will try generate PR when I find some time.
