Fix gsl version needed for fastANI

[shenwei356]

Describe your pull request here

fastANI needs libgsl.so.25, while the lastest gsl 2.7.1 provides libgsl.so.27. So the gsl version needed to be restricted to be >=2.6, <2.7.1.

gsl-2.7.1 => lib/libgsl.so.27
gsl-2.7   => lib/libgsl.so.25
gsl-2.6   => lib/libgsl.so.25
gsl-2.5   => lib/libgsl.so.23

A workaround solution:

mamba install gsl==2.7.0
mamba install fastani
