feat: create nwb acquisition module

[arjunsridhar12345]

This PR attempts to address #7. Uses information from this issue which has which raw streams to use: #5. The acquisition module currently in the NWB has these 4 streams associated with behavior:

• left_reward_delivery_time
• right_reward_delivery_time
• left_lick_time
• right_lick_time.

It sets up an acquisition builder module that can then be mapped directly to NWB without the need to take on dependencies from pynwb.

An initial example notebook can be found here on how to access the object:

UPDATE: Removed example notebook because it's redundant to the raw data loader. Renamed to go under an nwb module since this is will be primarily used for nwb packaging
