add validation on input read length for assemblies involving IDBA

[brettin]

Recipes involving IDBA should fail sooner, and with an appropriate message when reads are greater than 150bp.

Hi Tom,

I took a look; the three jobs had errors because IDBA was involved in those recipes and failed because > the read length was longer than 150bp. So that’s expected. Other assemblers in those jobs generated > contigs. I’ll check if there’s an update with IDBA.
