Added FlagWigwag.value getter

[bok-]

📒 Description

FlagWigwag is a way to get information about flags and to track changes to flags over time, eg:

let wigwag = flagPole.subgroup.$myFlag

The FlagWigwag has access be able to look up the current value as part of its internal workings, but if you wanted to get the current value you'd need to:

// Get it alongside the wigwag
let (value, wigwag) = (flagPole.subgroup.myFlag, flagPole.subgroup.$myFlag)

// Get it from a publisher or AsyncSequence
let value = wigwag.first() ?? wigwag.defaultValue
let value = await wigwag.first(where: { _ in true }) ?? wigwag.defaultValue

This PR adds a FlagWigwag.value getter to close this gap:

let wigwag = flagPole.subgroup.$myFlag
let value = wigwag.value
