[Feature]: Create Error Span Kind

[areibman]

💡 Feature Description and Proposed Solution

Create an easy way to create and log errors as spans. This could be potentially BOTH a decorator and a standalone function. For example:

from agentops.sdk.decorators import error

@error
def log_error():
    ...

error()

OR

agentops.error(name="...", message="...")
