check_sample_in_multiqc_report() handling numeric sample names

[cyouh95]

When sample names are numeric, samples below may be numeric while reformatted_multiQC_samples is string type, resulting in it thinking there are missing samples when there isn't:

dp_tools/dp_tools/bulkRNASeq/checks.py

Line 1528 in 6307508

missing_samples = set(samples) - set(reformatted_multiQC_samples)

Suggested fix:

missing_samples = set(map(str, samples)) - set(reformatted_multiQC_samples)
