INSTALLATION: Add R dependencies to R package so they are installed automatically

[fmaguire]

Please add the R package dependencies to the DESCRIPTION e.g. dplyr, tidyverse, UpSetR etc so they are automatically installed when the user runs devtools::install_github("ramadatta/CPgeneProfiler")

Optional: consider making a bioconda package (conda isn't exclusively python and there are a ton of non-python bioinformatics tools within bioconda now) that will install the tool AND the external BLAST+ dependency: the bioconda docs and a simple R package that already exists can be used as a template.

[ramadatta]

We agree with reviewer's comment. These issues have been fixed.

R package dependencies are added to DESCRIPTION file. We are hopeful that this would ensure smooth installation of the package using devtools.

Additionally, in the README page under the Requirements section, we have provided the R commands to install relevant dependencies.

At this juncture, in view of submission time lines, we could not readily come up with bioconda package. But, we will surely consider making a bioconda package with all the dependencies in the upcoming versions of the package.
