allow user to download/symlink files

The following command downloads the file and writes to output:

type_creator download <url-to-file>  --output <folder/file>

The following command does the same, but writes the file to a central location, and then symlinks from central location to output

type_creator download -s  <url-to-file>  -o <folder/file>

so the above command would write the file to:

path="$HOME/.typeaware/downloads/<url-to-file>"

then it would symlink it to local:

ln -s $path $output

The purpose is to allow the user to download types from libraries so they can use the types in their codebase. If the file in github is a .zip file, they would have to pass an extract option:

type_creator download --extract -s  <url-to-file>  -o <folder/file>
