Features

Use native terminal cursors in text inputs by default.
Use native terminal cursor on date prompts when an optional style sheet for the selected cursor token was defined as None. The default behavior is still a custom style sheet which highlights the two columns pertaining to a date, instead of using a native cursor which can only highlight one column.
Respect NO_COLOR environment variable when prompt uses the default render configuration.

Fixes

By using a new method to identify the length of the rendered prompt, we avoid possible rendering errors (edge cases) when a string can not render into a single line in the terminal due to a smaller width. Inner calculations could previously predict that the rendered string would fit, by considering that 1 grapheme = 1 column width, but this is not true for e.g. emojis. Now we use unicode_width to fix this behavior.
Fixed case where Select/MultiSelect prompts were panicking when a user pressed the down arrow on an empty list, which happens when a filter input does not match any options. #30
Fixed incorrect indexes on the output of MultiSelect prompts, where the indexes inside a ListOption struct were relative to the output instead of the original input vector. #31
Fixed case where IO errors due to not finding a tty devices were not being catched and transformed to InquireError::NotTTY. #28
