feat: add dynamicName in schema returned by getSchema

[CJ42]

What kind of change does this PR introduce (bug fix, feature, docs update, ...)?

⭐ Feature

What is the current behaviour (you can also link to an open issue here)?

#400 introduced a change in the getSchema function that replaces the dynamic part <...> with the actual hex value in the name of the schema.

However, this causes a problem has the schem returned cannot be used anymore as it will the name now contains a hex value and ERC725.encodeData or ERC725.decodeData will not find the name anymore when searching through the data keys.

What is the new behaviour (if this is a feature change)?

• Add an extra property dynamicName returned in the schema when dealing with Mapping and MappingWithGrouping data keys when using getSchema(...)
• Preserves the full name of the data key to address the issue mentioned above.
• Export getSchema function standalone, to make it available outside of class instance
