New pipeline first releases 🎉

These pipelines just had their very first release.

• nf-core/proteinannotator v1.0.0 — Generation of sequence-level annotations for amino acid sequences
• nf-core/seqinspector v1.0.0 — Dedicated QC-only pipeline for sequencing data. The pipeline will run a (potentially large) set of QC tools and can output global and group specific Multiqc reports. The pipeline is targeting core facilities or research groups with larger sequencing throughput.
