Some tests are still not passing, though.
A migration script was added to migrate serialized grids from
pre-scrollback to the current format. The script is included with this

A few tests in grid/tests.rs were removed due to becoming irrelevant.
Padding can be configured by using the `padding` field in the config
file, like so:
padding:
x: 2
y: 2
which would result in a 2px padding within each side of the window.
ANSI escape sequences like `\x1b[48;5;10m` were not supported until now.
Specifically, the second attribute, 5, says that the following attribute
is a color index.
The ref tests were updated since `enum Color` variants changed.
