Contextualizing validateSession

• validateSession returns a Boolean, result, indicating the validity of a given session key instance. It takes:
  • Account config object:
    • name - string.
    • version - string.
    • ownerAddress - string.
    • biconomyApiKey - (optional), string. It should only be used if you’d like to use a Biconomy Paymaster.
  • Array of sessions:
    • Session object:
      • validUntil - integer.
      • validAfter - integer.
      • sessionValidationModule - string.
      • sessionKeyDataInAbi (alternative: sessionKeyData) - array.
