In Lyrohk/cruncher: Crunchbase API v4.0

#' Function to lookup and paginate through a single card for a single event over the Entity Lookup API Endpoint
#'
#' Takes the entity id to lookup a card and paginate through the entities and parse them into a data.frame
#'
#'@param event_card card field of interest that will be returned. Only one please!
#'@param event_id UUID or permalink of the event you wish to look up
#'@param please_parse Logical. By default TRUE and will parse your data from a list of data.frames to a final data.frame with empty elements dropping out.
