Allow easy printing ranges of objects

[pwojcikdev]

This is a small addition to logging framework that allows to quickly print a range of objects as an array. From what I heard native support for printing ranges is coming with C++23, until then this should work out of the box with most types in our codebase.

Example usage:

node.logger.debug (nano::log::type::tcp_channels, "Channels: {}", nano::streamed_range (channels | std::views::transform ([] (auto const & entry) {
	return entry.channel;
})));

Only after implementing this, I realized that it's possible to do this out of the box without having to wait for C++23, relying on built-in fmt library range printing:

node.logger.debug (nano::log::type::tcp_channels, "Channels [{}]: {}", channels.size (), channels | std::views::transform ([] (auto const & entry) {
	return nano::streamed (entry.channel);
}));

Both approaches work, up to you whether it's worth merging this one.
