par2create should use more memory

The man page says:

       The "-m" option controls how much memory par2 uses. It defaults to 16
       MB unless you override it.

It doesn't say why one would want to control it, but a little experimenting shows that this seems to be a space-time tradeoff. (Not too surprising considering the algorithms involved.)

Given that par2create can take a very long time on gigabytes of data, and given that 16MB is *really* small in 2010, when even cheapo netbooks come with 1 or 2GB of RAM, and given that no one in their right mind would be running par2create except on a reasonably powerful machine (so several gigabytes of RAM), it seems to me that the default setting is a tradeoff that made sense a decade or two ago but no longer, and should be drastically increased. 128MB doesn't seem unreasonable to me. (Heck, cellphones like the iPhone come with more RAM than that.)
