feat: dump logs from web apps

[weboko]

Description

It is not possible to get logs from js-waku retrospectively (env variable should be set and node re-run).

User Story

• As a consumer of js-waku lib, I want to be able to get logs, so that I can read them or share with other people.
• As Waku CC, I want to be able to easily navigate logs that are shared to me or that I retrieved from debugging.

Proposed Solution / Feature Design

Provide API to trigger during run time in Browser to download logs from js-waku in an application.
optional - For NodeJS allow to save files into a file.
Example: waku.dumpLogs() -> triggers download of a file in browser.

Add configuration to js-waku that will allow to change verbosity level - add verbosity option to createLightNode:

• env is set AND option provided - use verbosity and print logs;
• env is set AND no option provided - print logs with default verbosity;
• env is off AND no option - no logs;
• env is off AND option provided - print logs;
