Mabs 2.28

1. Fixed a bug that was causing Mabs-flye to ignore results of the last point (the tenth point if using "--maximum_number_of_points_to_try 10"). That bug was introduced in Mabs 2.24. The bug might make some assemblies slightly worse than they could have been.
2. Since Mabs 2.24, Mabs-flye determines the option with which it gives reads to Flye, based on the median read accuracy. After a series of experiments, I decided to change the scheme that was used in Mabs 2.24. Now the Flye option depends on the median read accuracy as follows:
   (0%; 95%] - "--nano-raw"
   (95%; 99.8%] - "--nano-hq"
   (99.8%; 100%] - "--pacbio-hifi"
