In electionsBR: R Functions to Download and Clean Brazilian Electoral Data

#' Download data on local candidates' personal financial disclosures
#'
#' \code{personal_finances_local()} downloads and aggregates the data on local candidates' personal financial disclosures. The function returns a \code{data.frame} where each observation corresponds to a candidate's property.
#'
#' @note For the elections prior to 2000, some information may be incomplete.
#'
#' @param year Election year. For this function, only the years 1996, 2000, 2004, 2008, 2012, 2016 and 2020
#' are available.
#' 
#' @param uf Federation Unit acronym (\code{character vector}).
#'
#' @param ascii (\code{logical}). Should the text be transformed from Latin-1 to ASCII format?
#'
#' @param encoding Data original encoding (defaults to 'Latin-1'). This can be changed to avoid errors
#' when \code{ascii = TRUE}.
#' 
#' @param export (\code{logical}). Should the downloaded data be saved in .dta and .sav in the current directory?
#' 
#' @param temp (\code{logical}). If \code{TRUE}, keep the temporary compressed file for future use (recommended)
#'
#' @details If export is set to \code{TRUE}, the downloaded data is saved as .dta and .sav
#'  files in the current directory.
#'
#' @return \code{assets_candidate_local()} returns a \code{data.frame} with the following variables:
#'
#' \itemize{
#'   \item DATA_GERACAO: Generation date of the file (when the data was collected).
#'   \item HORA_GERACAO: Generation time of the file (when the data was collected), Brasilia Time.
#'   \item ANO_ELEICAO: Election year.
#'   \item DESCRICAO_ELEICAO: Description of the election.
#'   \item SIGLA_UF: Units of the Federation's acronym in which occurred the election.
#'   \item SQ_CANDIDATO: Candidate's ID ID attributed by TSE.
#'   \item CD_TIPO_BEM_CANDIDATO: Code of the property.
#'   \item DS_TIPO_BEM_CANDIDATO: Description of the property.
#'   \item DETALHE_BEM: Addional details of the property.
#'   \item VALOR_BEM: Value, in current Brazilian reais, of the property.
#'   \item DATA_ULT_TOTALIZACAO: Date of the last totalization in that city and zone.
#'   \item HORA_ULT_TOTALIZACAO: Time of the last totalization in that city and zone.
