Added the slice method to the ap.String class (v4.0.27)

[simon-ritchie]

Since version 4.0.27, the ap.String's slice method has been added:

The slice method slices a string with the specified start and end indices.

import apysc as ap

...

string: ap.String = ap.String("012345")
result_string: ap.String = string.slice(start=0)
ap.assert_equal(result_string, "012345")

result_string = string.slice(start=1)
ap.assert_equal(result_string, "12345")

result_string = string.slice(start=0, end=2)
ap.assert_equal(result_string, "01")

result_string = string.slice(start=2, end=4)
ap.assert_equal(result_string, "23")
