v1.27: Maven package + ExtendLicense method + remove commons-codec

This release introduces the following changes:

1. We dropped commons-codec and replaced with a built in library in Java 8. Java 7, which is deprecated, required this dependency.
2. GetMachineCode is cross platform when called with v=3. Calling with v=2 will use the older version that did not include Mac and Linux.
3. oshi-core is optional. To avoid it, you can just call GetMachineCode with v=2 (Win) or v=3(Win+Mac+Linux).
4. If you use oshi-core, we upgraded it to a newer version to fix issues on newer platforms.
5. Introduced ExtendLicense method.

The package can be installed using Maven Central as per instructions on this page: https://central.sonatype.com/artifact/io.cryptolens/cryptolens/overview. This release includes a jar file as well.

Thanks to @sbraconnier, @sergey-oplavin and @stokpop.

v1.26: Update to HasFeature method

Minor update to HasFeature method and update of the gson library.

v1.25: Update method to obtain UUID

This version changes the way UUID is computed on Windows with v=2 (i.e. when either Helpers.GetMachineCode or Helpers.IsOnRightMachine is called with version parameter set to 2). Instead of using WMIC, the following command is used instead:

cmd /c powershell.exe -Command "(Get-CimInstance -Class Win32_ComputerSystemProduct).UUID"

Please note that in case of an error when retrieving the UUID, null will be returned.
