the export similarity index for the trade data and will return a ESI matrix if you have many commodities

ESI(
  trade_data,
  commodity_codes,
  Year = TRUE,
  partner_average = TRUE,
  country_names = NULL
)

`trade_data`	the tibble covnerted by the polish_data function
`commodity_codes`	the codes of the commodities based on which the ESI is calculated
`Year`	split the trade_data by year variable or not, if true the final output will be a list of ESI matrices, otherwise just a single matrix
`partner_average`	if true, it will combine all the partners(importers here) together to calculate the trade value or volume, otherwise the final ESI index will be the average of the ESI for each importer

a list of ESI matrices if the Year parameter is true, otherwise a single matrix
