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.
Builds made with ghc 9.10+ and the 'debug' build flag, will show
(some kind of, partial) stack traces when the program ends with an
error. (And also will have ghc-debug support enabled.)
The stack traces will probably improve in due course.
--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.
Older ghc versions should also still build cleanly (tested with 9.8 so far).
I don't like enabling CPP in so many modules but it's easier that
figuring out how to do it with base-compat; hopefully no noticeable
compilation impact.
When built with the ghcdebug flag and started with --debug=-1 (or -2
to pause at startup, or -3 to pause before exit), hledger can be
controlled by ghc-debug clients like ghc-debug-brick or a custom
ghc-debug query script.
Also, refactor version string code.
Note the headErr/tailErr calls will print stack traces if they fail
(small ones: five lines, one of which is the useful location info),
which may or may not be best UX.
Hledger.Utils.Debug.traceOrLog was logging when it should trace and vice versa.
This affected a warning which Hledger.Data.Valuation.pricesShortestPath
should display if encountering a pathologically long (>1000) price chain.
Also note some oddities about that warning.
- omit balance assertions
- replace more currency symbols, and match within symbols like C$
- do more account validation, and error if conversion is too hard
- backslash-escape double quotes and backslashes in payee and note
