Switch over to github.com/sijms/go-ora/v2 (#312)

* switch over to github.com/sijms/go-ora/v2
* rip stuff out of the build process (travis, rpm downloads, etc)
* modify docker files to not rely on oci.pc
* windows validation completed; push up multi-arch build
* bump version to 0.5.0

-First, download Oracle Instant Client 64-Bit version basic and sdk versions.
-
-Extract client (for example: **C:\oracle\instantclient_18_5**) and extract SDK to the same folder (**C:\oracle\instantclient_18_5\sdk**)

-    setx CGO_LDFLAGS "-LC:\oracle\instantclient_18_5 -loci"
-
-Then install GCC (like MSYS2 64 bit in **c:\msys64**)
-
-Run the MSYS2 MINGW64 terminal and set dependencies packages:
-
-- Update pacman:
-
-  pacman -Su
-
-- Close terminal and open a new terminal
