Support percents that are not multiplied by 100.

Generally, I want to handle formatting in the front-end code, not in Cube. For instance, if I want to display a number as a percentage in a table, then Cube will provide a ratio measure, and I'll turn it into a percentage string in the table column definition using Intl.NumberFormat. In particular, I expect Cube to provide a raw ratio, not a ratio multiplied by 100. This is consistent with the behavior of both Intl.NumberFormat and Excel, which will both turn .1 into 10% and 10 into 1000%.

However, Cube's percent formatter will format .1 as 0.10% rather than as 10%. This causes incorrect values to be displayed in the playground.

Describe the solution you'd like

Either a new format (e.g. percentNormalized) or a configuration option indicating that percent members are not multiplied by 100.
