Implement BSON Deserialization Logic and Tests

[7uperior]

This commit introduces several key components for BSON deserialization:

• Modified De.jl to include new deserialization functionality.
• Added DeBson.jl implementing the BSON deserialization interface.
• Created test.bson to provide data for testing deserialization.
• Added test/De/DeBson.jl comprising tests for the deserialization logic.
• Updated test/runtests.jl to include BSON deserialization tests.

These changes address tasks from issue #20, focusing on crafting a BSON deserialization interface, building maintainable and efficient logic, and developing a robust test suite to ensure the functionality is working as expected.

Hi, @7uperior! Thank you a lot for the BSON implementation. I have several suggestions to make it more in line with the library.
