T003: Missing data related to the mode "Road" and mode "Total Inland FT"

[hlinero]

Issue regarding https://stats.oecd.org/Index.aspx?DataSetCode=ITF_GOODS_TRANSPORT#

Rationale 1: Mode "Road" and Vehicle Type (VT) "All" is broken down into two VTs: "Road freight transport for hire and reward" and "Road freight transport on own account." There are years in which the "All" VT is presented but one if its components is missing.

Rationale 2: Just as mentioned before, the "Inland" mode has "All" as VT. However, the components that make up the "All" include the VT "Pipeline," "Inland Waterway," "Rail," and "Road ALL". There are years in which the "All" VT is presented but one if its components is missing.

Below is the list of countries

- 1970 - 2002 --> Road data is missing

Currently, the issue is handled in the code https://github.com/transportenergy/database/blob/master/item/historical/scripts/T003.py

The procedures to fix this problem are the following:

1. ITF correct these errors in their data and republish correct data https://stats.oecd.org/Index.aspx?DataSetCode=ITF_GOODS_TRANSPORT#
2. Implement code change https://github.com/transportenergy/database/blob/master/item/historical/scripts/T003.py removing the cleaning scripts associated with this problem
3. Regenerate a new merged dataset
