process substitution?

not sure how hard this would be to implement:

Currently get a seg fault. 

```
paladin align -t 4 -u 2 data/uniprot_sprot.fasta <(cat soil_S29_merged.assembled.fastq soil_S29_merged.unassembled.forward.fastq soil_S29_merged.unassembled.reverse.fastq)
[M::index_load_from_disk] read 0 ALT contigs
Segmentation fault (core dumped)
```
