4.3

Changelog:

• pre-allocated buffers to reduce memory usage, avoid fragmentation and finally drop malloc().
  With this change, the default PJON codebase will need more memory than the previous releases, but can be tuned to fit the requirements. To reduce the memory consumption simply pre-define MAX_PACKETS and PACKET_MAX_LENGTH constants to fit your needs before PJON.h inclusion. For example if your device transmits up to one packet, you can limit MAX_PACKETS to 1.

Bugfix:

• info_overhead function definition bugfix
• acquire_id experimental functionality removed
