Constantly moving mobile nodes and Thompson Sampling support

Following major changes were implemented:

• added Thompson Sampling algorithm
• added fully moving nodes in the predefined (custom rectangular) area
• implemented random placement of the nodes based on a uniform distribution
• coordinates of end nodes are sent in a payload
• implemented a free path loss to make an RSSI calculation more realistic and rewrite SNR calculation
• added new cases for collision count and total message count (collision occurs whenever a message is lost, e.g. low RSSI is considered collision)
• removed power coefficient as it is currently of no use (values are relative, never absolute)
• fixed known bugs and added minor improvements
