Functions
int	rlenc (char *infile, int nrows, int ncols, varfl **vals, size_t *nvals)
	Runlength-encodes a radar image.
int	rlenc_compress_line (int line, unsigned char *src, int ncols, varfl **dvals, size_t *nvals)
	Encodes one line of a radar image to BUFR runlength-code.
int	rldec (char *outfile, varfl *vals, size_t *nvals)
	Decodes a BUFR-runlength-encoded radar image.
int	rlenc_from_file (char *infile, int nrows, int ncols, varfl **vals, int *nvals, int depth)
	Runlength-encodes a radar image from a file to an array.
int	rldec_to_file (char *outfile, varfl *vals, int depth, int *nvals)
	Decodes a BUFR-runlength-encoded radar image to a file.
int	rlenc_from_mem (unsigned short *img, int nrows, int ncols, varfl **vals, int *nvals)
	This function encodes a radar image to BUFR runlength-code.
int	rldec_to_mem (varfl *vals, unsigned short **img, int *nvals, int *nrows, int *ncols)
	Decodes a BUFR-runlength-encoded radar image to memory.
int	rlenc_compress_line_new (int line, unsigned int *src, int ncols, varfl **dvals, int *nvals)
	Encodes one line of a radar image to BUFR runlength-code.
void	rldec_decompress_line (varfl *vals, unsigned int *dest, int *ncols, int *nvals)
	Decodes one line of a radar image from BUFR runlength-code.
void	rldec_get_size (varfl *vals, int *nrows, int *ncols)
	Gets the number of rows and columns of a runlength compressed image.
