add logger with loglevel support

Pull Request Template

Description

The logger supports different log levels, enabling developers to control the verbosity of log messages based on their requirements.

Logger Implementation

The Web SDK Logger is implemented as part of the Web SDK package. It provides methods for setting the log level and logging messages at various levels of severity.

Log Levels

The following log levels are supported:

Verbose: enables full logging - shows/prints all console.info, console.warn, console.error messages
Info: shows/prints all console.info, console.warn, console.error messages
Warning: shows/prints all console.warn, console.error messages
Error: default.shows/prints all console.error messages.
None: disables all logging.

Usage

Setting Log Level

set the logLevel method inside init options

branch.init(
    branch_key,
    options: {
        logLevel: 'verbose',
        timeout: 500,
        retry_delay: 400
    },
    callback(err, data),
);
