Accessing a DataFrame with an out of bounds range should raise #1005

Today if a range extends past the end of a DataFrame, we filter those columns out.

df = Explorer.DataFrame.new(a: [1, 2, 3])
df[1..1]
# #Explorer.DataFrame<
#   Polars[0 x 0]
# >

Per the discussion here, we think we should raise instead.
