Feature/custom fields (#27)

This PR adds 115 custom fields using the `mex:` namespace.

These custom fields are derived from the
[3.4.0](https://github.com/robert-koch-institut/mex-model/releases/tag/3.4.0)
version of the MEx metadata model.

There is some validation implemented using little effort but this should
not be required as incoming data will already have been validated using
the model.

The `mex:identifier`  field is the only `required` custom field.

The [resource
types](https://inveniordm.docs.cern.ch/customize/vocabularies/resource_types/)
vocabulary has been replaced with 11 MEx entity types. Please verify
that these are the correct entity types.

The custom nested field class `MultiLanguageTextCF` is modelled on the
MEx
[text](https://github.com/robert-koch-institut/mex-model/blob/main/mex/model/fields/text.json)
field.

### Templates
Three templates has been amended, `records/detail.html` which includes
`records/details/mex_details.html` and `records/macros/mex_detail.html`
only in order to list custom fields the same way Datacite fields are
listed by default on the landing page.

The templates have also been changed to not expect a `props` property
defined in the `RDM_CUSTOM_FIELDS_UI` config variable. In other words,
if these amended templates were not used, Jinja would throw an error
expecting each field in that config variable to have a `props` property
set.

## Unresolved
This PR does not have unit tests. They are coming soon in a PR for
importing data.

There are still decisions to be made on the searchability of these
custom fields, if and then how they are searched on or faceted.
