-The market sync could crash when calculating the USD price if the base pair of the markets_page.default_exchange.trading_pair value was not found in coingecko's vs_currencies list from https://api.coingecko.com/api/v3/simple/supported_vs_currencies (for example, using USDT as the default base pair). A different calculation is now used in this case which does not require any additional api credits to be used.
-As of Feb 2024 the free "keyless" coingecko api will be deprecated and will likely stop working. There is a free demo api key that can be used which can now be plugged into the explorer settings to allow the coingecko api to continue working.

-The previous market price calculation setting was hardcoded to only display market and USD prices for a single exchange and trading pair which was not very accurate for coins listed on multiple exchanges or with multiple trading pairs. The new default is to average the market prices for all supported exchanges and trading pairs
-The coingecko market price option was added to allow fetching the market price directly from the coingecko api instead of calculating it via supported exchanges known to the explorer
-Added a new root setting option for default_coingecko_ids which allows presetting symbols to their associated internal coingecko id to help prevent matching to the wrong currency with same symbol via coingecko api calls
-Fixed an issue where the explorer would fail to start with an enabled exchange that had no defined trading pairs
-Market sync now sets the last USD price based on the default market pair even if it is not BTC
-Removed the coindesk api which was only really useful for getting the USD price of BTC
-Added a couple coingecko apis which are used to get the current USD value of the default market pair
-Updated the readme, settings file comments and info/api page with better verbiage regarding the market price which was previously only measured in BTC
