Feature request: binstr format with group and extra lines options

[H0smax]

I am using a Cyclone II FPGA which needs datafile to be the same size as defined by software. For example, a memory of 1024 words of 16 bits should look like this in the input file:
0011...0100 // 16 bits per line
0100...0000
... // until 1024 lines

where each line represent a single word.
But binstr only outputs the information in a single line.

I would like to do something like -f binstr,group:16 and get this kind of output. Also, specifying how much lines after the program ends would be perfect (like -f binstr,group:16,lines:1024 and fills with 0 until reaching 1024 lines).
