data size bug

[wgchaoer]

when dataType: int16
failed to scrape target '192.168.10.248:502' with module 'fake': failed to scrape metrics for module 'fake': metric 'LN_temperature', address '30001': modbus: response data size '1' does not match count '2'
when dataType: int32
failed to scrape target '192.168.10.248:502' with module 'fake': failed to scrape metrics for module 'fake': metric 'LN_temperature', address '30001': modbus: response data size '1' does not match count '4'

dataType endianness ，I have tried all available value types for both methods.
It is normal for modpoll Windows version to collect data from this device.
