Add node:traffic_calming=choked_table to lookups.dat

[ProBackup-nl]

Nodes with both vertical and lateral deviation. Therefore different cost assignment, thus as a new line.
Tag choked_table is in the wiki.

Please stop adding lookups direct, it should be discussed in #458.
As you see this has a long history. And if ok then I add this in my repository. So we have only one new version to check.

And value choker_table is already used as alias
