report: fix pe_start column type from NUM to SIZ

The 'pe_start' column was incorrectly marked as being of type NUM.
This was not correct as pe_start is actually of type SIZ, which means
it can have a size suffix and hence it's not a pure numeric value.

Proper column type is important for selection to work correctly, so we
can also do comparisons while using suffixes.

This is also important for new "json_std" output format which does not
put double quotes around pure numeric values. With pe_start incorrectly
marked as NUM instead of SIZ, this produced invalid JSON output
like '"pe_start" = 1.00m' because it contained the 'm' (or other)
size suffix. If properly marked as SIZ, this is then put in double
quotes like '"pe_start" = "1.00m"'.
