Helper function to get the MaxEnt java executable and install it in the right locations for zoon modules that use `dismo::maxent` and `biomod2`.
GetMaxEnt()
Since MaxEnt may not be distributed other than via the MaxEnt
website, users must download the file themselves and place it in the
right location for R packages to access it. This function helps with that.
Just run GetMaxEnt() and follow the prompts in the terminal.
