Empty metadata assignments read by Nanopore parser lead to arrayOutOfBoundsException

[wow-such-code]

Expected Behaviour

The nanopore parser warns and does not validate data in case metadata fields are empty.

Observed Behaviour

The nanopore parser fails while trying to parse empty metadata fields, without throwing an informative warning

Steps to reproduce

Possible reasons

core-utils-lib/src/main/groovy/life/qbic/utils/NanoporeParser.groovy

Line 100 in 5a070db

finalMetaData[split[0]] = split[1]

There are already methods that test if some of the metadata is empty (see finalizeMetadata()), but the aforementioned code runs earlier, leading to an error.
