Hello there!

My question is, I have a dataset in a csv file and I would like to know what is the best way to load it in memory.  
As an example, lets say I have the following columns:

```julia
time -> datetime
mag_field -> float
mot -> boolean

```

I know I could easily use

```julia
using DataFrames
using CSV

file = "data.csv"
my_data = CSV.File(file)

```

But what is the best way to, for example, when importing, letting CSV.File know what are the data types inside my file, get the column names properly.
