Add APR moving average line to chart

[tab00]

Is your feature request related to a problem? Please describe. APR's can change a lot day-to-day, making it difficult to compare and decide which assets on which blockchains would be good to supply.

Describe the solution you'd like Show an additional moving average line (e.g. 20-period) to smoothen out the bumps.

Consider also adding longer-term moving average lines e.g. 50-, 100-, 200-period.

Consider also using exponential moving average to give more weight to more recent data.
