feat(table): additional help keys

[digitalkaoz]

adds additional keys to the table component:

// additional short help keys
	tbl := table.New(
		table.WithAdditionalShortHelpKeys([]key.Binding{
			key.NewBinding(key.WithKeys("s"), key.WithHelp("s", "shortkey")),
		}),
	)

        tbl.HelpView()

// additional full help keys
	tbl := table.New(
		table.WithAdditionalFullHelpKeys([][]key.Binding{
			{
				key.NewBinding(key.WithKeys("f"), key.WithHelp("s", "fullkey")),
			},
		}),
	)
        tbl.Help.ShowAll = true

        tbl.HelpView()

note: the handling of those keys must be done in your userland code!
