feat: update sic_classification to match the 1987 revision of the US SIC codes

[jdhoffa]

As documented here: https://www.osha.gov/data/sic-search

Note: it seems that the original sic_classification bridge was referencing the South African SIC standard, as documented here:
https://www.statssa.gov.za/additional_services/sic/mdvdvmg4.htm#MAJOR%20DIVISIONS,DIVISIONS%20AND%20MAJOR%20GROUPS

We likely should assess if we want to continue to support that dataset (and probably need to name it something more specific to identify what it refers to).

Maybe closes #356

[jdhoffa]

Based on the decision here: https://dev.azure.com/RMI-PACTA/2DegreesInvesting/_workitems/edit/10292#30590656
We will update the sic_classification dataset to the US SIC codes for clarity.

If removing the SA SIC codes causes any issues, it is expected that the functionality soon to be introduced by RMI-PACTA/r2dii.match#447
will handle this.

In particular, users will be able to flag that classification systems are missing.

@jacobvjk This is ready for review

Closes #356 and #344

Given that we are using a 1987 revision here, I am wondering if SIC was largely superseded by other systems in the US and only the name persisted in other jurisdictions. Not for this PR, but definitely something to consider

Probably!
