Log Message:
tio: update to 1.34.

Changes since tio v1.33:

 * Fix setspeed2 compilation

 * Only apply color formatting when using color option

   To help the color blind who may use custom terminal foreground /
   background colors.

 * Update README

 * Add '-c, --color' option

   Allow user to select which ANSI color code to use to colorize the tio
   text. To successfully set the color the color code must be in the range
   0..255.

   If color code is negative tio will print all available ANSI colors.

   The default color is changed to bold white to make tio defaults usable
   for most users, including color blind users.

 * Fix setspeed2 check

 * Fix meson header check string

 * Reintroduce long timestamp format

   But make the timestamp format RFC3339 compliant instead. The RFC states:

   NOTE: ISO 8601 defines date and time separated by "T".
         Applications using this syntax may choose, for the sake of
         readability, to specify a full-date and full-time separated by
         (say) a space character.

   This way we keep the information specified by ISO 8601 but make it more
   human readable which is better for the console output.

 * Update version year

 * Fix TTY device listing on Darwin. (#136)

 * Fix TCGETS2 search on Darwin.
