flaky load behavior

```{r}
> sc %>% etl_load(years = 2019, months = 4:7)
Loading 4 file(s) into the database...
Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, :
line 48 did not have 90 elements
In addition: Warning message:
In etl::smart_upload(obj, src = src, tablenames = "statcast", ...) :

Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, :
line 48 did not have 90 elements
> sc %>% etl_load(years = 2019, months = 4)
Loading 1 file(s) into the database...
Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, :

> sc %>% etl_load(years = 2019, months = 5)
Loading 1 file(s) into the database...
> sc %>% etl_load(years = 2019, months = 6)
Loading 1 file(s) into the database...
> sc %>% etl_load(years = 2019, months = 7)
Loading 1 file(s) into the database...
> sc %>% etl_load(years = 2019, months = 4)
Loading 1 file(s) into the database...
```

Perhaps need to add some robustness checks or run `etl_init()`?
