Close #6272 (which is sub-issue of https://github.com/NVIDIA/spark-rapids/issues/6149 ). Implemented casting bool/int8/int16/int32/int64 -> {string, float, double(float64), timestamp}. When casting `Long -> timestamp`, we need overflow checking. And if there is long-overflow,...

A sub-issue of #6149 . Implement casting bool/int8/int16/int32/int64 -> {string, float, double(float64), timestamp}, totally 20 cases.

[FEA] Support date casting for ORC reading.

A sub-issue of #6149 . While reading ORC files, implement casting `date` to `{timestamp, string}`. Type `date` in scala-spark is actually `javq.sql.Date`, see https://spark.apache.org/docs/latest/sql-ref-datatypes.html. In python-spark, it's actually `datetime.date`.

If I want to do something when the timer is zero, what should I do? Thanks.

Does this lib just support channels = 2?

I have noticed that: ```cpp struct adpcm_context { struct adpcm_channel channels [2]; int num_channels, lookahead, noise_shaping; }; ``` and piece of code in `adpcm_converter`: ```cpp if (WaveHeader.NumChannels < 1 ||...
