Replace uniVocity CSV library with maintained alternative

[UltraCharge99]

Your repository dependents on the uniVocity CSV library:

tablesaw/core/pom.xml

Lines 96 to 100 in 8e07825

	<dependency>
	<groupId>com.univocity</groupId>
	<artifactId>univocity-parsers</artifactId>
	<version>2.9.1</version>
	</dependency>

Unfortunately, the uniVocity CSV library is not maintained anymore. For reference and possible alternatives, see uniVocity/univocity-parsers#534.
