Support JSON dictionary along JSON files as input to the ArgoValidator

[gmaze]

Hi,
It would be very nice for cross-tools analysis if the ArgoValidator().validate() method could take an dictionary object, not necessarily a json file.
I propose here some update to the method to support this.

The use case would typically be when some sensor metadata will be loaded from a manufacturer API or any sensor metadata files with argopy to validate such data.

I also modified the init to be able to import the validator directly, such a nice feature needs the front row ;-)

from argopy import OEMSensorMetaData
obj = OEMSensorMetaData().from_rbr(208380)

from argo_metadata_validator import ArgoValidator
ArgoValidator().validate(oem.to_dict())

PS:
What I have in mind here, is to be able to use argo_metadata_validator in argopy for internal format validation. Cf, ongoing work on sensors at: euroargodev/argopy#532.

And since you support also float and platform schema, this should be used elsewhere in the future.

Hi @gmaze, thanks for this. It's definitely a good idea to add in. I'll find some time in the next week to have a proper look through this and get it merged in
