[FEATURE]: [Bambora] Currency Unit Conversion

[Sakilmostak]

:memo: Feature Description

• Each currency can be described in terms of base or minor units.
• For instance, when dealing with USD currency, the Cent is considered as the minor unit, while the Dollar is considered the base unit.
• In Hyperswitch, the amount value is expected to be always provided in minor units.
• For example: In USD, If the amount is 1 in base unit (Dollar), then it will be equivalent to 100 in minor units (Cent)
• Some of the connectors integrated require the amount to be converted to a desirable unit before being passed to them.
• We have functions to_currency_base_unit and to_currency_lower_unit in place to convert the minor unit amount to its decimal equivalent and vice versa. These conversions are handled explicitly based on the connector.

:hammer: Possible Implementation

• ConnectorCommon trait have been implemented for the connector.
• This trait contains get_currency_unit method. This method needs to be implemented.
• It will define what type of conversion needs to be done during connector_router_data creation. Concurrently handle the creation of connector_router_data to be passed for the connector request body creation.
• You can check this PR for further reference https://github.com/juspay/hyperswitch/pull/2196

:bookmark: Note: All the changes needed should be contained within hyperswitch/crates/router/src/connector/

Sure @speedhs , I have assigned this issue to you

[speedhs]

Hey! Using the other prs as a reference I have made some changes to the code. Can you guide me as to how I can check if its working fine? Possibly by calling some API?

Hey @speedhs Create a payment via hyperswitch, and match the amount you are passing in your request with amount you are getting in connector response. Both should be same.
