README.md, package specs: Various tweaks
- Don't enumerate the types of SIMD instructions that libjpeg-turbo
supports, as this can change without notice.
- Use more clear terminology when describing support for libjpeg v7/v8
features ("libjpeg" is, colloquially but not officially, the name for
the IJG's software, whereas the "libjpeg API" refers to our emulation
of said software.)
- "PhotoShop" = "Photoshop" (StudLy Caps Police)
- Adjust dynamic library versions to reflect the addition of
jpeg_read_icc_profile() and jpeg_write_icc_profile() in
libjpeg-turbo 2.0.x.
