Feature: support for SNMP sequences

[llamafilm]

I'd like to monitor SNMP data for an LED video wall. The wall is made of 72 "display units", each of which contains 12 "cells". Each cell reports its temperature, indexed by the Unit ID. Since the temperature is defined as a DisplayString, I use the following override to turn it into float:

    overrides:
      ledCellStatusTemperatureCell1:
        regex_extracts:
          '':
            - regex: '(.*)'
              value: '$1'

That works well, but I have to copy this 12 times in the generator. It would be nice for this app to parse sequences

What device/snmpwalk OID are you using?

Sony PROV1-LEDDISPLAY-MIB.txt 1.3.6.1.4.1.122.8501.3.128.13.1

Another idea, which would avoid this issue: Could we automatically try to parse strings as floats, and fall back to string if it fails.
