[R] serialize does not work as expected

[Jeff King]

compact sequences are actually an ALTREP object. I do not know if there is
any standard way to do it, but here is a trick for what you want.

```
> x <- 1:3
> .Internal(inspect(x))
@0x00000196bed8dd78 13 INTSXP g0c0 [NAM(7)]  1 : 3 (compact)
> x[1] <- x[1]
> .Internal(inspect(x))
@0x00000196bef90b60 13 INTSXP g0c2 [NAM(7)] (len=3, tl=0) 1,2,3
```

Best,
Jiefei
