[performance] Improve speed of our CRC-64 hasher (#624)

Modify the `Crc64` implementation to use splicing in order to process
data in a smaller number of iterations, at the expense of a bit more
memory for the extra tables.  A quick test of calculating checksum for
a 1GB file shows a ~5.5x improvement:

	Allocating 1043332542 bytes to hold file data
	Reading file 'android-ndk-r21-linux-x86_64.zip' into memory
	Calculating checksum using the old method... Hash: 197913BA13B9A1CC; Time: 00:00:04.0649818
	Calculating checksum using the new method... Hash: 8203D033719B6B96; Time: 00:00:00.7251845

The calculated hash is different (although still stable and correct)
because the new code uses tables generated using a slightly different
set of parameters.  Instead of using a single lookup table, the new
code takes the [slice-by-8 approach][0] which processes 8 bytes at a
time, using 8 lookup tables instead of one.

[Pycrc][1] was used to generate the `crc_update()` and `crc_reflect()`
methods, which were then ported to C# in [`gen-crc-tables.cs`][2], via:

	pycrc.py --model crc-64-jones --std=C99 --algorithm bbf --generate {h,c} --reflect-out=true

Because the calculated hash now differs, we've changed the output
prefix from `crc64` to `c64r2`, to make the change slightly more
prominent and obvious.

Preliminary integration into xamarin-android shows build improvements
for a small Xamarin.Forms app, Debug configuration:

  * First build:

        Time Elapsed 00:00:36.74 (master)
        Time Elapsed 00:00:34.43 (crc64)

  * Incremental build (`.cs` file touched):

        Time Elapsed 00:00:08.68 (master)
        Time Elapsed 00:00:08.51 (crc64)

And for `<GenerateJavaStubs/>` task, which outputs 9.5MB of data:

  * First build:

        606 ms  GenerateJavaStubs                          1 calls (master)
        570 ms  GenerateJavaStubs                          1 calls (crc64)

  * Incremental build:

        702 ms  GenerateJavaStubs                          1 calls (master)
        617 ms  GenerateJavaStubs                          1 calls (crc64)
