Query features by ID

[clarisma]

Allow access to features by ID:

n = features.node(123)
w = features.way(123)
r = features.relation(123)

Challenges:

• GOLs currently do not have an ID index, so queries would be relatively slow
• However, performance could be increased significantly using "spatial hinting" (user supplies a coordinate or bbox that overlaps with the desired feature)

In case anyone else stumbles across this feature request in search for a solution, one possible workaround is: next(f for f in my_features.ways if f.id == 123)

It doesn't use an index so it may be slow but it will return the way 123 in one line, if it exists.
