newFee can equals maxStreamingFeePercentage in StreamingFeeModule

[gzliudan]

In StreamingFeeModule, streamingFeePercentage can be equal to maxStreamingFeePercentage when initialize:

require(_settings.streamingFeePercentage <= _settings.maxStreamingFeePercentage, "Fee must be <= max.");

But when updateStreamingFee _newFee can't be equal to _maxStreamingFeePercentage:

require(_newFee < _maxStreamingFeePercentage(_setToken), "Fee must be less than max");

It seems that use <= to check is better.
