feat: allow customization of status module block edge separators

[JefeDavis]

this change allows you to adjust the edges of the status modules array separate from the modules inside the array

Set the module edge separator

set -g @catppuccin_status_modules_right_separator_left  " "  # default is @catppuccin_status_left_separator
set -g @catppuccin_status_modules_right_separator_right " "  # default is @catppuccin_status_right_separator
set -g @catppuccin_status_modules_left_separator_left   " "  # default is @catppuccin_status_left_separator
set -g @catppuccin_status_modules_left_separator_right  " "  # default is @catppuccin_status_right_separator

Set the module edge colors

set -g @catppuccin_status_modules_right_separator_left_color  "color"  # default is @catppuccin_[module_name]_color
set -g @catppuccin_status_modules_right_separator_right_color "color"  # default is @catppuccin_[module_name]_color
set -g @catppuccin_status_modules_left_separator_left_color   "color"  # default is @catppuccin_[module_name]_color
set -g @catppuccin_status_modules_left_separator_right_color  "color"  # default is @catppuccin_[module_name]_color

additionally i have included a second commit that allows you to adjust the [ current | default ]current_window[ color | background ]

these all have sane defaults and fallback options so this should not effect and existing users
Here is an example
