Also, start from 1 in the positive direction, instead of 5, since that
is more how the thing works (sorry, mathematician brain).
Additionally, adds some extra information in the comments:
information about how long the code would take if one actually sets
count to 2,5 * 10^12, and adding a plus in front of the 4/1 to show that
that is in fact the first element of the "plus" side.
Finally, add an (floating point) error to the debug print.
Parse the command line following the code from the Zig compiler cli.
Use the args iterator instead of slice, and use while instead of for
loop.
Use the new std.mem.cutPrefix instead of the custom function prefix.
Move Context struct to the top.
