consider using imported parameters directly from the `config` object, rather than copying them to global environment

Currently, parameters imported from the config.yml
are copied into global variables one-by-one here, and then used via these global variables. It may be preferable to access the parameters directly from the config
object rather than creating numerous global variables. e.g.
change this...
data_prep_outputs_path <- config$data_prep_outputs_path
...
currencies_data_path <- file.path(data_prep_outputs_path, "currencies.rds")
to this...
currencies_data_path <- file.path(config[["data_prep_outputs_path"]], "currencies.rds")

I'm all for this. Noting that where we currently do the conversion from config elements to top-level R objects (x <- config$x
) should be replaced with a check that the elements we are using exist in the config, as a way to preserve fail-fast behavior
expected_keys <- c(
"asset_impact_data_path",
"factset_data_path",
"data_prep_outputs_path",
...
)
stopifnot(all(expected_keys %in% names(config)))
