encoding/base64: optimize decodemap memory set
The existing implementation has an execution time higher in the benchmark than this one.
This is an optimized implementation using the copy() function and a constant 256 bytes string with the values to be copied.
```
name old time/op new time/op delta
NewEncoding-4 329ns ± 1% 231ns ± 1% -29.72% (p=0.008 n=5+5)
name old speed new speed delta
NewEncoding-4 778MB/s ± 1% 1108MB/s ± 1% +42.29% (p=0.008 n=5+5)
