Subject: [PATCH] Support floating point numbers in instruments CSV

When I generate Instruments data with the sample interval set to 40
microseconds instead of 1 ms and then export the data, I get Self values
that are sometimes floating point fractional numbers of ms.

Modify the regex to account for the potential of these numbers.
