TIMESTAMP (-101), BINARY_DOUBLE (101) and BINARY_FLOAT (100) are handled in OracleDialect
## What changes were proposed in this pull request?
When a oracle table contains columns whose type is BINARY_FLOAT or BINARY_DOUBLE, spark sql fails to load a table with SQLException
```
java.sql.SQLException: Unsupported type 101

## How was this patch tested?
I updated a UT which covers type conversion test for types (-101, 100, 101), on top of that I tested this change against actual table with those columns and it was able to read and write to the table.
