Adding compatibility with Azure AD

Azure AD has a specific pattern when specifying patch operation names.

As you can see here https://docs.microsoft.com/en-us/azure/active-directory/app-provisioning/use-scim-to-provision-users-and-groups#step-2-understand-the-azure-ad-scim-implementation

Don't require a case-sensitive match on structural elements in SCIM, in particular PATCH op operation values, as defined in https://tools.ietf.org/html/rfc7644#section-3.5.2. Azure AD emits the values of 'op' as Add, Replace, and Remove.

This version allows the use of a capital letter for operations names.
An issue is open #5 to be case insensitive for patch operation names.

Increase coverage and clean the code.

Clean the code and increase coverage to be at 100%.
