No query options for GetIssuesForSprint

## Describe the bug
`GetIssuesForSprint` and `GetIssueWithContext` are missing query options.
It prevents lot of useful filtering, like issue assignee, reported, etc..

## To Reproduce
Just try to filter issues by assignee or other filter

## Expected behavior
I would expect `GetIssuesForSprint` get a query options like others functions

## Possible Solution
Add query options to the function

## Your Environment
* go-jira version (git tag or sha): v1.13.0
* Go version (`go version`): 1.15

## Additional context
I'm trying to filter issues by assignee to create a custom board and I find myself needs to do it by code instead if using the filtering Jira is providing by it's API.
