Room77: Check Inbound Capacity

[rootzoll]

The POS sould check the remaining inbound capacity (biggest inbound on any channel open). At least when bar tender puts in amount that is higher than that limit it should let know that this amount is not possible at the moment and give options: make on-chain, open channel to node or manage inbound capacity.

[arcbtc]

Added x2 functions. nodedetails, which returns the pubkey, channels, etc, and nodecheck, which takes the pubkey and checks capacity.

Both run in setup, to use what nodecheck returns:

JsonObject node = doc["node"]; long node_last_update = node["last_update"]; // 1567549590 const char* node_pub_key = node["pub_key"]; // "03d34c207eecb9045228c9f835d7a2ed950f2ba03a4f173ed6fd3a895cf00de201" const char* node_alias = node["alias"]; // "room77"

const char* node_addresses_0_network = node["addresses"][0]["network"]; // "tcp" const char* node_addresses_0_addr = node["addresses"][0]["addr"]; // "someip:9777"

const char* node_color = node["color"]; // "#68f442"

int num_channels = doc["num_channels"]; // 32 const char* total_capacity = doc["total_capacity"]; // "80037668"
