fix: Big Number support for incrementors in redis

[mkeen]

Big Numbers (mostly seen in token total supply, etc) will cause crashes unless we use INCRBYFLOAT.

RESP3 lays out how much memory we can use for Big Numbers (64 bits)

You can try the command with and without INCRBYFLOAT using a large 64 bit unsigned integer or signed integer to see the difference it makes.

redis> INCRBY mykey 18446744073709551615
redis> error: "ERR value is not an integer or out of range"

redis> INCRBYFLOAT mykey 18446744073709551615
redis> success: "350488137400481481280"

redis> HINCR myhash field 18446744073709551615
redis> error: "ERR value is not an integer or out of range"

redis> HINCRBYFLOAT myhash field 18446744073709551615
redis> success: "350488137400481481280"
