Describe the bug
i'm unable to query an object using easysnmp, but i can with snmpget. the device is a raritan PDU

To Reproduce

snmpget -v2c -c public 192.168.1.1 -M +$PWD/mibs/raritan -m ALL -On measurementsOverCurrentProtectorSensorValue.1.18.rmsCurrent
.1.3.6.1.4.1.13742.6.5.3.3.1.4.1.18.1

when i query the same object in easysnmp and dump the variable, i get

<SNMPVariable value="NOSUCHINSTANCE" (oid=.1.3.6.1.4.1.13742.6.5.3.3.1.4.1.18, oid_index=4, snmp_type="NOSUCHINSTANCE")

if i change the 'measurementsOverCurrentProtectorSensorValue.1.18.rmsCurrent' object in my easysnmp query to 'measurementsOverCurrentProtectorSensorValue.1.18.1' it does return a value
