Added exception handler function

[keshavdalmia10]

Description

Added exception handler function onError in IAlgorithm interface

Related Issue

Motivation and Context

Now even if there is an runtime error in the algorithm, we can open and close the positions

Requires Documentation Change

How Has This Been Tested?

Tested by running a demo algorithm with a runtime error. The program executes the end_of_algorithm method now

Thank you for the contribution @keshavdalmia10!
Sorry but this is not a good first issue really, it's a feature which requires a higher degree of depth in the implementation. Please take a look at existing "good first issue" labeled issues instead
