[REQUEST] Progress.tasks should return a Dict instead of a List

[digital-idiot]

Currently Progress.tasks method (property) returns a list of tasks. This makes querying a task with their task_id a bit cumbersome. Consider the scenario when some tasks are removed which causes mismatch between task_id and list indexes. Since the task_id of each task is unique why not return a dict in the format {task_id: <task_object>, ...} instead. That would be much more convenient and intuitive. Consider the following snippet:

from time import sleep
from rich.progress import Progress


with Progress() as phost:
    t1 = phost.add_task(description="Foo:", total=30)
    t2 = phost.add_task(description="Bar:", total=50)
    for i in range(30):
        phost.update(t1, advance=1)
        sleep(0.1)
    if phost.tasks[t1].finished:
        phost.remove_task(t1)
    for j in range(50):
        phost.update(t2, advance=1)
        sleep(0.1)
    if phost.tasks[t2].finished:  # Index error here!!
        phost.remove_task(t2)
