transparency on start

[yazgoo]

WIP (points to a branch of tuikit): depends on skim-rs/tuikit#44

Adds a flag so that skim does not clear the whole screen before displaying

example

Running in this branch:

clear
blockish /home/yazgoo/Pictures/vimpapers/73lfih7qkrr61.png
echo "\e[0;0f"
./target/debug/sk --margin 20,20,20,20  --no-clear-start

Results in:

new flag

--no-clear-start will disable clearing the screen and enter alternate screen, (see skim-rs/tuikit#44)

Hi, this breaks my old usage. E.g. run sk --height 20 < some_list when there are more than 20 lines below, before this pr it returns to the line where it starts and prints the result, but after this pr, it seems to jump to the middle of my terminal screen. (--no-clear-start works fine however.)

Hi, sorry about this, will look at it
