`Redis.scan` cursor parameter requires a number

[Max Goodhart]

scan takes a number cursor:

redis/redis.ts

Lines 2278 to 2281 in fb773be

 scan( 
   cursor: number, 
   opts?: ScanOpts, 
 ) { 

The cursor returned by this method is a string, so it needs to be coerced to pass back into the next iteration of scan.

In contrast, hscan takes a string cursor:

redis/redis.ts

Lines 2288 to 2292 in fb773be

 sscan( 
   key: string, 
   cursor: number, 
   opts?: SScanOpts, 
 ) { 

Should the cursor param of scan be changed to a string?
