Function parameterize

fn parameterize(
    channels_params: &mut ChannelPaddingInstructions,
    config: &ChannelConfig,
    dormancy: Dormancy,
    netdir: &NetParamsExtract,
) -> Result<Option<ChannelPaddingInstructionsUpdates>, Bug>

Converts config, dormancy, and netdir, into parameter updates

Calculates new parameters, updating channels_params as appropriate. If anything changed, the corresponding update instruction is returned.

channels_params is updated with the new parameters, and the update message, if one is needed, is returned.

This is called in two places:

1. During chanmgr creation, it is called once to analyze the initial state and construct a corresponding ChannelPaddingInstructions.

2. During reconfiguration.
