feat: Add option to ignore xml pattern restrictions

[tefra]

📒 Description

xsdata is generating xsd pattern restrictions, but the binding module still can't handle them, they are there just for reference.

The generator also will reset the datatype to simple string, in order to avoid parsing/converting certain values like decimals incorrectly eg \d{2}.\d{1}.

Resolves #720

🔗 What I've Done

This pr adds an option to ignore-patterns.
They won't be generated and the processor won't try to reset the attr type.
