Issue: Fail to process all bond callbacks in ``bondpy``

[sosoeeee]

I am currently using bondpy to create a Python lifecycle node as part of my development with the nav2 lifecycle manager. While the bond is formed successfully using bondpy, I encountered an issue where the node quickly dies due to a heartbeat timeout. After investigation, I discovered that bondpy fails to respond to all bond_status messages published by the lifecycle manager at high speed.

To resolve this issue, I referred to the implementation of bondcpp and increased the message buffer size from 1 to 100 in bondpy.
