Can we instead construct a slice and call DelSlice?

@trotterdylan was thinking same, but some tests are not passing:
--- FAIL: TestListDelSlice (0.00s)
list_test.go:122: TestListDelSlice([1, 2, 3, 4, 5], -1, 3) = [1, 2, 3, 4, 5], want [4, 5]
list_test.go:122: TestListDelSlice([1, 2, 3, 4, 5], 1, -3) = [1, 3, 4, 5], want [1, 2, 3, 4, 5]
from CPython:
>>> x=[1,2,3,4,5]
>>> x.__delslice__(-1, 3)
>>> x
[4, 5]
>>> x=[1,2,3,4,5]
>>> x.__delslice__(1, -3)
>>> x
[1, 2, 3, 4, 5]
>>>

@trotterdylan ok, I will keep index alignment before initiating Slice, it should be enough
