Remove the "Sum" column

[pomponchik]

Hello!

There is the table with some statistics in pepy.tech. An example for a my library:

Date	0.0.21	0.0.20	0.0.19	0.*	Sum	Total
2023-09-12	1	0	1	2	4	2
2023-09-11	7	3	9	64	83	64
2023-09-10	12	5	4	96	117	96
2023-09-09	8	5	3	18	34	18
2023-09-08	9	3	4	20	36	20
2023-09-07	9	5	4	38	56	38
2023-09-06	111	45	13	204	373	204
2023-09-05	50	66	7	162	285	162

As you can see, by default, the "Sum" column displays the sum of downloads of the last three versions of the library + all versions, including these three versions. That is, the numbers for the last three versions of the libraries are doubled.

Given that the same table contains the "Total" column, the "Sum" column looks useless and can be removed.
