+`build()` will now show a single summarized warning if samples have less than 50%
+of their abundance matched in the model database. Samples with no matches at all will
+be reported separately and removed from the manifest as those can not be used as an
+input to `grow()`.

+Made sure that progress bars are no longer spammed with logging messages in between.
