random nits and cleanups:

- make scalariform allow dangling parends

  sometimes I find this to be a useful way to indicate nesting:

  throw new Exception(
      “%s %s %s %s”.format(
          foo, bar baz, boo
      )
  )

- tweak comment about read-ID suffixes in FASTQ

- wrap a few long lines

- add docs to adamFastqLoad method
