Update to 1.1.0

Upstream changes:
cli 1.1.0

    cli has now functions to add ANSI styles to text. These use the crayon \ 
package internally, and provide a simpler interface. See the col_*, bg_*, \ 
style_* and also the make_ansi_style() and combine_ansi_styles() functions \ 
(#51).

    New is_dynamic_tty() function detects if \r should be used for a stream (#62).

    New is_ansi_tty() function detects if ANSI control sequences can be used for \ 
a stream.

    New ansi_hide_cursor(), ansi_show_cursor() and ansi_with_hidden_cursor() \ 
functions to hide and show the cursor in terminals.

    New make_spinner() function helps integrating spinners into your functions.

    Now symbol always uses ASCII symbols when the cli.unicode option is set to FALSE.
