GBP vs GBp

[Pathfinder075]

Ticker treats GBP and GBp the same, so total value and cost, end up being somewhat higher than they should be.

To Reproduce
Create a .ticker.yaml, place two stocks in, example VUAG.L and JEGP.L
Add in the Avg Cost for each one and the amount
JEGP.L will display thousands because the stock is in pence and VUAG.L will display as 100's because the stock is in pounds. This screws up the total value and cost entries as it sees JEGP.L as having a value measured in 1000's.
In the UK our stocks can be displayed on Yahoo Finance in two ways. GBP represents stocks measured in pounds, for example £100.10 (one hundred pounds and ten pence) or GBp which represents stocks measured in pence, for example 5000.50p (50 pounds and half a penny).

Expected behavior
Ticker would differentiate between a GBP and GBp stock. The measurement used is displayed at the top of the page in Yahoo Finance, but I don't know exactly how Ticker gets that information
