Previously, hledger could read CSV files containing non-ascii
characters only if they are UTF8-encoded. Now there is a new CSV
rule, encoding ENCODING, which allows reading CSV files with other
encodings.
This adds a dependency on the encoding library, which supports fewer
encodings than text-icu but does not require a third-party C library.
To avoid build issues on various platforms, we require version 0.10+.
This adds some use of the ImplicitParams language extension, required
by encoding's API, but only in a small code region.
This also changes the type of Reader's rReadFn; it now takes
a `Handle` rather than a `Text`, allowing more flexibility.
error' and usageError now redden and bolden the first line of error
messages, when ANSI codes are supported and permitted.
And warn goldens and boldens the first line of warning messages.
Hledger.Utils.IO's ansi style/color helpers now respect --color=yes,
so that eg `hledger --color=yes | less -R` shows bold headings as
you'd expect.
Hledger.Utils.IO.rgb' now takes Float arguments instead of Word8.
When using `less` as pager, if HLEDGER_LESS is defined, it will
provide the options (instead of LESS + hledger's extra options).
You can set your own preferred options here, or you can set it
equal to LESS to use exactly those options.

Currently this sets a rather ambitious set of options,
and overrides the existing LESS:
--chop-long-lines
--hilite-unread
--ignore-case
--mouse
--no-init
--QUIT-AT-EOF
--quit-if-one-screen
--RAW-CONTROL-CHARS
--squeeze-blank-lines
--use-backslash
--use-color
This fixes the error displayed when quitting the pager with long output.
It also replaces the pager lib with more robust homegrown pager utilities,
which should prevent a number of failure modes.
--color now also works in a config file, like --pager, except for two
cases: it does not affect colouring of debug output, or the colouring
helpers used in the check recentassertions error message.
