Modification not backward compatible in XsdRestriction (xsdParser 1.2.5+)

[mttfranci]

First of all, I would like to thank you for providing this very usuful xsd parser.

Describe the bug
Upgrading xsdParser version from 1.2.4 to 1.2.6, the return type of method getPattern() has been changed. (from single value to list).
Here is the commit introducing the breaking change :
859d897
This broke my software's build.

Expected behavior
Creating new method for new return type, flag the old one as deprecated and wait some time before removal.
Maybe using some sort of convention for breaking changes, for instance as in
semantic versioning
(Changing the major version when a new release is not backward compatible)

Library Version
Upgrading from 1.2.4 to 1.2.6

Additional context
Here is a sample of the code that broke :
AutodocAttribute line 95

Thanks again!

Hello,

Thanks for using the library! Yeah, you are right, I've accepted the PR and didn't think about backwards compatibility. I've released a new version, 1.2.7, with the old method as it was before the change and a new method getPatterns, so everyone should be happy :)

@lcduarte One more thing: could the old method be deprecated? I think making the patterns a list is a good change, but right now library users will only see this change "by coincidence". Adding a deprecated warning will make them aware of the good work being done here. :)

@SimonCockx I think the current solution is valid, both options are valid to be used, if the someone needs the list he'll look if another method is available.
