+Given a start height, an optional end height, and a Bitcoin network (`mainnet` or `testnet`), the function returns the block headers in the provided range. The range is inclusive, i.e., the block headers at the start and end heights are returned as well.
 An error is returned when an end height is specified that is greater than the tip height.
 
 If no end height is specified, all blocks until the tip height, i.e., the largest available height, are returned. However, if the range from the start height to the end height or the tip height is large, only a prefix of the requested block headers may be returned in order to bound the size of the response.
