Conversion from Oracle values to rust values.

Values in Oracle are converted to Rust type as possible as it can. The following table indicates supported conversion.

Oracle Type	Rust Type
character data types	String
"	i8, i16, i32, i64, isize, u8, u16, u32, u64, usize, f64, f32 by using `String.parse()`
"	Vec<u8> (The Oracle value must be in hexadecimal.)
"	Timestamp by `String.parse()`
"	IntervalDS by `String.parse()`
"	IntervalYM by `String.parse()`
numeric data types	i8, i16, i32, i64, isize, u8, u16, u32, u64, usize, f64, f32
"	String
raw	Vec<u8>
"	String (The Oracle value is converted to characters in hexadecimal.)
timestamp data types	Timestamp
"	String
interval day to month	IntervalDS
"	String
interval year to month	IntervalYM
"	String
Oracle object except Oracle collection	Object
"	String
Oracle collection	Collection
"	String
boolean (PL/SQL only)	bool

When chrono feature is enabled, the followings are added.

Oracle Type	Rust Type
timestamp data types	chrono::DateTime
"	chrono::Date
"	chrono::naive::NaiveDateTime
"	chrono::naive::NaiveDate
interval day to second	chrono::Duration

This conversion is used also to get values from output parameters.
