Have installation scripts fetch go depenencies

[EmperorDali]

We need to run this during the install:

go get github.com/shenwei356/xopen
go get github.com/shenwei356/bio/seq

[Arkadiy-Garber]

As of November 2019, the installation script does not fetch these dependencies.

causing this error:

Processing dependencies for dashit-filter==2.0

cd misc && go build -o score_guides
score_guides.go:6:2: cannot find package "github.com/shenwei356/bio/seq" in any of:

make: *** [build-score-guides] Error 1

Thus, before running make, users must run the following three commands:

go get github.com/shenwei356/xopen
go get github.com/shenwei356/bio/seq
go get github.com/shenwei356/bio/seqio/fastx
