Add withMetrics1 method for partial binary compatibility

[Z1kkurat]

Motivation:
In an intermediate version 15.2.0 there were two methods for creating a metered producer:

• a deprecated withMetrics using MeasureDuration from smetrics
• withMetrics1 using MeasureDuration from cats-helper

There's only one withMetrics method now, using MeasureDuration from cats-helper.

The same goes for consumer: https://github.com/evolution-gaming/skafka/blob/v15.2.0/skafka/src/main/scala/com/evolutiongaming/skafka/consumer/Consumer.scala#L955-L969

If library A depends on v15.2.0 and calls withMetrics1(catshelper.MeasureDuration), and library B depends on A but evicts skafka to 16.0.0, then B calls A, A calls withMetrics1(catshelper.MeasureDuration), but there's no such method in skafka v16.0.0 (the only one present is withMetrics(catshelper.MeasureDuration)), so it fails with a runtime error.

This PR tries to fix that, at least partially.
