Improve open performance of S3 reader

Description

Due to missing information (the variables contained in the product) in the manifest file the NetCDF files need to be opened to retrieve this information. This slows down the opening process.

This can be solved by using a static look-up table in the reader.
This is not an ideal solution and therefore this issue shall be reported to the S3MPC.
