Amazon Athena JDBC Driver Wrapper Supporting the 'metis' Package

## Description

Contents of the Amazon Athena JDBC Driver
<https://docs.aws.amazon.com/athena/latest/ug/connect-with-jdbc.html>
provided to support functions in the 'metis' package. Version number
reflects the version number of the included 'JAR' file.

## IMPORTANT

Until a release of 'rJava' newer than '0.9.10' is on CRAN signals sent
from interrupting Athena JDBC calls crash the R interpreter. You therefore
need to set the `-Xrs` option to avoid signals being passed on to the JVM
owner. That has to be done _before_ `rJava` is loaded so you either need
to remember to put it at the top of all scripts _or_ stick this
in your local `~/.Rprofile` and/or sitewide `Rprofile`:

```r
options(
"java.parameters" = c(getOption("java.parameters", default = NULL), "-Xrs")
)
```
## What's Inside The Tin?

The following functions are implemented:

- `athena_supported_types`: Retrieve the current supported type names in Athena
- `metis_jar_path()` : Retrieve the fully-qualified path to the included Athena JAR file
- `simba_driver_version`: Retrieve the version of the Simba Athena JDBC driver included with the package

## Installation

```{r eval=FALSE}
devtools::install_git("https://git.sr.ht/~hrbrmstr/metis-jars")
# OR
devtools::install_gitlab("hrbrmstr/metis-jars")
# OR
devtools::install_github("hrbrmstr/metis-jars")
```

## Usage

```{r}
library(metis.jars)

# current verison
packageVersion("metis.jars")
```

```{r}
simba_driver_version()

athena_supported_types()

metis_jar_path()
```
