Documentation: minSdkVersion should be 19

[anidotnet]

In my android device with API 18:

java.lang.NoClassDefFoundError: java.nio.charset.StandardCharsets
        at org.h2.mvstore.MVStore.writeStoreHeader(MVStore.java:920)
        at org.h2.mvstore.MVStore.<init>(MVStore.java:399)

java.nio.charset.StandardCharsets is added in API level 19, see https://developer.android.google.cn/reference/java/nio/charset/StandardCharsets.html

So minSdkVersion should be 19 or higher for android devices if excludes jackson-datatype-jsr310:

   implementation ('org.dizitart:nitrite:3.2.0'){
        exclude group:"com.fasterxml.jackson.datatype", module:"jackson-datatype-jsr310"
    }
    implementation('org.dizitart:potassium-nitrite:3.2.0'){
        exclude group:"com.fasterxml.jackson.datatype", module:"jackson-datatype-jsr310"
    }

highlight it in README.md is recommended.
