Look into if we need to rename number of contigs field in metadata

[apetkau]

Description of feature

One of the saved metadata fields is named Number of Contigs Greater Than Or Equal To 300 bp. Ideally, I'd like to rename to include the StarAMR prefix, but since this has a user-configurable value (300 bp), it is harder to rename.

Look into if we need this field renamed later on. It is much easier to identify than other fields as being associated with StarAMR because of it's length.
