Re: [dxwg] Add support for spatial resolution specification via skos:ConceptScheme (#1263)

My proposal is to add a new DCAT property (e.g. `dcat:spatialResolution`) with the domain of `dcat:Dataset` and the range of `skos:Concept`, which would support connecting to a concept representing a spatial hierarchy level such as NUTS2, NUTS3, LAU (formerly also LAU1 and LAU2), etc.

I am currently not aware of any existing code list, which could be universally used for this (not even, for instance, in EU), since even the now discontinued LAU2 level corresponds to the level of municipalities, but we could go further to the level of parts of towns, streets, etc.). There is, however, a local code list for this in Czechia, which could be used, and I think there could be similar code lists elsewhere.

A specific example could be (with a fictitious NUTS3 level IRI):
```turtle
@prefix dcat: <http://www.w3.org/ns/dcat#> .
@prefix dct: <http://purl.org/dc/terms/> .

<https://data.gov.cz/zdroj/datové-sady/http---vdb.czso.cz-pll-eweb-package_show-id-290038r05> a dcat:Dataset;
    dct:title "Cizinci podle státního občanství, věku a pohlaví v okresech - rok 2004"@cs,
              "Foreigners: by citizenship, age and sex in districts - year 2004"@en ;
    dct:accrualPeriodicity freq:ANNUAL ;
    dct:publisher <https://rpp-opendata.egon.gov.cz/odrpp/zdroj/orgán-veřejné-moci/00025593> ;
    dct:spatial <https://linked.cuzk.cz/resource/ruian/stat/1> ;
    dcat:spatialResolution <http://data.europa.eu/nuts/scheme/2016/level/3> .
```
indicating, that the dataset contains records for NUTS3 regions.

Note that currently, there are no actual IRIs for NUTS/LAU levels, only for NUTS classifications themselves as the levels of individual codes are specified as literals.
