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.

Prevously the test waited for the first two peer connections rather than waiting for the two expected peers to connect.
Commonly the bootnode will connect inbound to peerB at the same time as peerB connects outbound to the bootnode, resulting in two connection events.
