Use custom tokenization function for NetCDFDataProxy objects

[bouweandela]

🚀 Pull Request

Description

Use custom tokenization function for NetCDFDataProxy objects. This speeds up loading small NetCDF files. With the multiple_cubes.nc file from #6223, the speedup is 10 to 20 %, though in the benchmarks below it is not really significant.
