And reconfigure tests to set this to 1. The target tx size can finally
be set to a proper value (100k) and the compression ratio as well to our
currently best estimate of 0.4.

The respective environment variable is OP_BATCHER_MAX_CHANNEL_DURATION.

The new channel configuration parameter MaxChannelDuration can be used
to set a max duration of L1-blocks for which a channel should be kept
open. This can be used to ensure that a channel is not kept open for too
long during times of low L2 tx volume.

It's only used internally and shouldn't be part of the channel builder's
public API.
