Upgrading from v5 or less to v6 or above

If you are using a version of this library older than v6.0.0 and want to move to a newer version of this library, you'd have to modify the import paths from something like:

    "github.com/jedib0t/go-pretty/list"
    "github.com/jedib0t/go-pretty/progress"
    "github.com/jedib0t/go-pretty/table"
    "github.com/jedib0t/go-pretty/text"

to:

    "github.com/jedib0t/go-pretty/v6/list"
    "github.com/jedib0t/go-pretty/v6/progress"
    "github.com/jedib0t/go-pretty/v6/table"
    "github.com/jedib0t/go-pretty/v6/text"

I'd recommend you fire up your favorite IDE and do a mass search and replace for all occurrences of jedib0t/go-pretty/ to jedib0t/go-pretty/v6/. If you are on a system with access to find, grep, xargs and sed, you could just run the following from within your code folder to do the same:

find . -type f -name "*.go" | grep -v vendor | xargs sed -i 's/jedib0t\/go-pretty\//jedib0t\/go-pretty\/v6\//g'

If you are on macOS, you'll have to use sed -i '' instead of sed -i.
