increase_reads_in_percent calculations are incorrect.

[alxmrtn]

On line 46 in calculators.py in the function increase_reads_in_percent, you have

increase = int(
    float(current_provisioning)*(float(percent)/100+1))
updated_provisioning = current_provisioning + increase

it should just be

increase = int(float(current_provisioning)*(float(percent)/100))
updated_provisioning = current_provisioning + increase

or alternatively

updated_provisioning = int(float(current_provisioning)*(float(percent)/100+1))

Thanks for the feedback @alxmrtn. I have released Dynamic DynamoDB version 1.3.2 to PyPI containing this fix. Just do a pip install -U dynamic-dynamodb to upgrade to the latest release.
