PayControl SDK version 5.2
	5.2.206 [Mar 16, 2021]
		Brings some significant changes from version 5.0, including the following:
			- Spongy Castle is removed as a dependency. Now crypto providers are taken from Android SDK.
			- Now binary data for transactions is stored in file system (app cache directory), not in RAM.
			  Thus, there are almost no restrictions for attachment sizes.
			- Operations are introduced. Operation is generally a bunch of related transactions 
			  which can be processed altogether. 
			  Refer to documentation on PCOperationsManager and PCOperation for more details.
			- eKYC module is added. This module provides functionality for remote identification which
			  can be used as a preliminary step before issuing the keys.
			  Refer to documentation on PCKYCManager and PCKYCSession for more details.
			- Key backups are introduced. Now, the key can be backed up and restored later (provided that
			  the server supports this functionality and backups are enabled).
			  Refer to documentation on PCUserBackupData and PCUserRestore for more details.
			- Key pair is now generated and stored in Android KeyStore for devices running Android 6 or newer.
